_isLabelSet: boolean
 
Protected

Gets a value that indicates if the label is locally set.

Source: javascript/web/pentaho/type/_type.js, line 640

Overrides: pentaho.type.mixins.DiscreteDomain.Type#_isLabelSet

alias: __nonEmptyString

Gets the alias for the identifier of this type.

The alias of a type can only be specified when extending the ancestor type.

This attribute is not inherited.

When unspecified, defaults to null.

Source: javascript/web/pentaho/type/_type.js, line 503

Overrides: pentaho.type.mixins.DiscreteDomain.Type#alias

See also:  pentaho.type.Type#id

ancestor: pentaho.type.Type

Gets the parent type in the current type hierarchy, if any, or null.

The root type returns null.

Overrides: pentaho.type.mixins.DiscreteDomain.Type#ancestor

See also:  pentaho.type.Type#root , pentaho.type.Type#hasDescendants

application: object

Gets or sets the application attribute of this type.

The application property serves as a collection of properties specific to the container application that can be modified via the Configuration Service.

Setting this to a Nully value will have no effect.

Source: javascript/web/pentaho/type/_type.js, line 658

Overrides: pentaho.type.mixins.DiscreteDomain.Type#application

category: __nonEmptyString

Gets or sets the category associated with this type.

The category is used primarily to group similar types (or instances of) in a user interface.

Attempting to set to a non-string value type implicitly converts the value to a string before assignment.

Setting this to undefined causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is null.

Setting this to null or to an empty string clears the attribute and sets it to null, thus ignoring any inherited value.

Source: javascript/web/pentaho/type/_type.js, line 727

Overrides: pentaho.type.mixins.DiscreteDomain.Type#category

See also:  pentaho.type.Type#isBrowsable , pentaho.type.Type#ordinal

context: pentaho.type.Context

Gets the context that defined this type class.

Source: javascript/web/pentaho/type/_type.js, line 181

Overrides: pentaho.type.mixins.DiscreteDomain.Type#context

countMax: undefined | number | pentaho.type.spec.PropertyDynamicAttribute.<number>

Gets or sets the maximum number of elements that properties of this type can have.

A non-negative integer.

Note that this attribute is taken together with the isRequired and the countMin attributes to determine the effective element count range of a property type.

This attribute is Dynamic

When a dynamic attribute is set to a function, it can evaluate to a different value for each complex instance.

When a dynamic attribute is set to a value other than a function or a Nully value, its value is the same for every complex instance.

This attribute is Monotonic

The value of a monotonic attribute can change, but only in some, predetermined monotonic direction.

In this case, a property type having a countMax of 5 can later be changed to have a countMax of 3. However, a property type having a countMax of 5 can no longer "go back" to have a greater countMax, like 7. The countMax attribute can only change to a lower value.

Because this attribute is also dynamic, the actual countMax values are only known when evaluated for specific complex instances. This behavior ensures that monotonic changes are deferred until evaluation. No errors are thrown; non-monotonic changes simply do not take any effect.

This attribute is Inherited

When there is no local value, the effective value of the attribute is the inherited effective value.

The first set local value must respect the monotonicity property with the inherited value.

Other characteristics

The value got by the attribute is the last set local, value, if any - a function, a constant value; or, undefined, when unset.

When set to a Nully value, the set operation is ignored.

When set and the property already has descendant properties, an error is thrown.

The default (root) countMax attribute value is Infinity.

Source: javascript/web/pentaho/type/property.js, line 1214

See also:  pentaho.type.Complex#countRangeOf , pentaho.type.spec.IPropertyTypeProto#countMax

countMaxOn:

Evaluates the value of the countMax attribute of a property of this type on a given complex value.

This method is used to determine the effective element count range and is not intended to be used directly.

Source: javascript/web/pentaho/type/property.js, line 1198

See also:  pentaho.type.Property.Type#countMax

countMin: undefined | number | pentaho.type.spec.PropertyDynamicAttribute.<number>

Gets or sets the minimum number of elements that properties of this type must have.

A non-negative integer.

Note that this attribute is taken together with the isRequired attribute to determine the effective element count range of a property type.

This attribute is Dynamic

When a dynamic attribute is set to a function, it can evaluate to a different value for each complex instance.

When a dynamic attribute is set to a value other than a function or a Nully value, its value is the same for every complex instance.

This attribute is Monotonic

The value of a monotonic attribute can change, but only in some, predetermined monotonic direction.

In this case, a property type having a countMin of 1 can later be changed to have a countMin of 2. However, a property type having a countMin of 2 can no longer go back to have a lower countMin, like 0. The countMin attribute can only change to a greater value.

Because this attribute is also dynamic, the actual countMin values are only known when evaluated for specific complex instances. This behavior ensures that monotonic changes are deferred until evaluation. No errors are thrown; non-monotonic changes simply do not take effect.

This attribute is Inherited

When there is no local value, the effective value of the attribute is the inherited effective value.

The first set local value must respect the monotonicity property with the inherited value.

Other characteristics

The value got by the attribute is the last set local, value, if any - a function, a constant value or undefined, when unset.

When set to a Nully value, the set operation is ignored.

When set and the property already has descendant properties, an error is thrown.

The default (root) countMin attribute value is 0.

Source: javascript/web/pentaho/type/property.js, line 1128

See also:  pentaho.type.Complex#countRangeOf , pentaho.type.spec.IPropertyTypeProto#countMin

countMinOn:

Evaluates the value of the countMin attribute of a property of this type on a given complex value.

This method is used to determine the effective element count range and is not intended to be used directly.

See also:  pentaho.type.Property.Type#countMin

declaringType: pentaho.type.Complex.Type

Gets the complex type that declares this property type.

Source: javascript/web/pentaho/type/property.js, line 220

defaultValue: pentaho.type.Value | pentaho.type.spec.PropertyDynamicAttribute.<pentaho.type.spec.UValue>

Gets or sets the default value of properties of this type.

The default value is the "prototype" value that properties of this type take, on complex instances, when the property is unspecified or specified as a Nully value.

The value null is a valid default value.

This attribute is Dynamic

When a dynamic attribute is set to a function, it can evaluate to a different value for each complex instance.

When a dynamic attribute is set to a value other than a function or a Nully value, its value is the same for every complex instance.

Get

When got and the default value (local or inherited) is not an instance of the value type (local or inherited), null is returned.

Set

When set and the property already has descendant properties, an error is thrown.

When set to null, it is respected.

When set to the control value undefined, the attribute value is reset, causing it to assume its default value (yes, the default value of the default value attribute...):

  • for root property types or properties with a locally set valueType, the default value is null
  • for other property types, the default value is the inherited value.

When set to a function, it is accepted. For each complex instance, the function is evaluated and its result converted to the property type's valueType, using its Value.Type#to method. The conversion may be impossible and thus an error may be thrown.

When set to any other value, it is immediately converted to the property type's valueType.

Source: javascript/web/pentaho/type/property.js, line 510

See also:  pentaho.type.spec.IPropertyTypeProto#defaultValue

defaultView: string

Gets or sets the default view for instances of this type.

The identifier of the view's AMD module. If the identifier is relative, it is relative to sourceId.

Setting this to undefined causes the default view to be inherited from the ancestor type, except for the root type, Instance.type (which has no ancestor), where the attribute is null.

Setting this to a falsy value (like null or an empty string), clears the value of the attribute and sets it to null, ignoring any inherited value.

Source: javascript/web/pentaho/type/_type.js, line 973

Overrides: pentaho.type.mixins.DiscreteDomain.Type#defaultView

See also:  pentaho.type.Type#buildSourceRelativeId

defaultViewAbs: string

Gets the absolute view module identifier, if any.

A default view exists if property pentaho.type.Type#defaultView has a non-null value.

Source: javascript/web/pentaho/type/_type.js, line 1008

Overrides: pentaho.type.mixins.DiscreteDomain.Type#defaultViewAbs

See also:  pentaho.type.Type#defaultView

description: __nonEmptyString

Gets or sets the description of this type.

Attempting to set to a non-string value type implicitly converts the value to a string before assignment.

Setting this to undefined causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where this attribute is null.

Setting this to null or to an empty string clears the attribute and sets it to null, ignoring any inherited value.

Source: javascript/web/pentaho/type/_type.js, line 687

Overrides: pentaho.type.mixins.DiscreteDomain.Type#description

domain: undefined | Array.<pentaho.type.Element> | pentaho.type.spec.PropertyDynamicAttribute.<Array.<pentaho.type.Element>>

Gets or sets the list of valid values (or a function that evaluates to these) of properties of this type.

This attribute is Dynamic

When a dynamic attribute is set to a function, it can evaluate to a different value for each complex instance.

When a dynamic attribute is set to a value other than a function, its value is the same for every complex instance.

This attribute is Monotonic

The value of a monotonic attribute can change, but only in some, predetermined monotonic direction.

In this case, the list of valid values can only be successfully reduced.

When the valueType is an enumeration, the initial list of valid values is its domain.

Because this attribute is also dynamic, the actual domain values are only known when evaluated for specific complex instances. This behavior ensures that monotonic changes are deferred until evaluation. No errors are thrown; non-monotonic changes simply do not take any effect.

This attribute is Inherited

When there is no local value, the effective value of the attribute is the inherited effective value.

The first set local value must respect the monotonicity property with the inherited value.

Other characteristics

The value got by the attribute is the last set local, value, if any - a function, a constant value; or, undefined, when unset.

When set to a Nully value, the set operation is ignored.

When set and the property already has descendant properties, an error is thrown.

When the valueType is an enumeration, the values intersection preserves those which have a formatted value. When both instances have a formatted value, the one specified last wins.

The last specified domain determines the order.

domainOn:

Evaluates the value of the domain attribute of a property of this type on a given owner complex value.

Implements:
elemName: string

Gets the singular name of Property.Type list-elements.

Source: javascript/web/pentaho/type/property.js, line 185

Default Value: "property"

elemType: pentaho.type.Element.Type

The base element type of the singular values that the property can hold.

When the property is a list property, that list type's element type, pentaho.type.List.Type#of, is returned.

Otherwise, pentaho.type.Property.type is returned.

Source: javascript/web/pentaho/type/property.js, line 354

hasDescendants: boolean

Gets a value that indicates if this type has any descendant types.

Source: javascript/web/pentaho/type/_type.js, line 279

Overrides: pentaho.type.mixins.DiscreteDomain.Type#hasDescendants

See also:  pentaho.type.Type#ancestor

helpUrl: __nonEmptyString

Gets or sets a URL pointing to documentation associated with this type.

Attempting to set to a non-string value type implicitly converts the value to a string before assignment.

Setting this to undefined causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is null.

Setting this to null or to an empty string clears the attribute and sets it to null, ignoring any inherited value.

Source: javascript/web/pentaho/type/_type.js, line 763

Overrides: pentaho.type.mixins.DiscreteDomain.Type#helpUrl

id: __nonEmptyString

Gets the identifier of this type.

The identifier of a type can only be specified when extending the ancestor type.

The identifier is only defined for types which have an associated AMD/RequireJS module. However, note that all have a pentaho.type.Type#uid.

This attribute is not inherited.

When unspecified, defaults to the value of sourceId.

Source: javascript/web/pentaho/type/_type.js, line 416

Overrides: pentaho.type.mixins.DiscreteDomain.Type#id

See also:  pentaho.type.Type#sourceId

index: number

Gets the index of the property in the containing complex type.

Source: javascript/web/pentaho/type/property.js, line 232

inheritedStyleClasses: Array.<string>

Gets the style classes of this and any base types.

The returned array should not be modified.

Source: javascript/web/pentaho/type/_type.js, line 896

Overrides: pentaho.type.mixins.DiscreteDomain.Type#inheritedStyleClasses

instance: pentaho.type.Instance

Gets the prototype of the instances of this type.

Source: javascript/web/pentaho/type/_type.js, line 291

Overrides: pentaho.type.mixins.DiscreteDomain.Type#instance

isAbstract: boolean

Gets a value that indicates if this type is abstract.

This attribute can only be set once, upon the type definition.

Source: javascript/web/pentaho/type/_type.js, line 526

Default Value: false

Overrides: pentaho.type.mixins.DiscreteDomain.Type#isAbstract

isAdvanced: boolean

Gets or sets the isAdvanced attribute of this type.

Types with isAdvanced attributes set to false are typically immediately accessible to the user. An advanced type typically escapes the expected flow of utilization, yet it is sufficiently relevant to be shown in a user interface.

Setting this to a Nully value causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is false.

Source: javascript/web/pentaho/type/_type.js, line 830

Overrides: pentaho.type.mixins.DiscreteDomain.Type#isAdvanced

See also:  pentaho.type.Type#isBrowsable

isApplicable: undefined | boolean | pentaho.type.spec.PropertyDynamicAttribute.<boolean>

Gets or sets a value or function that indicates if properties of this type are applicable.

When a property is not (currently) applicable, then it does not apply, as it does not make sense in a certain situation. It may only be applicable when another property of the complex type has a specific value, for example.

When a property is not currently applicable, its value is not significant and, as such, any validations concerning it are not performed.

This attribute is Dynamic

When a dynamic attribute is set to a function, it can evaluate to a different value for each complex instance.

When a dynamic attribute is set to a value other than a function or a Nully value, its value is the same for every complex instance.

This attribute is Monotonic

The value of a monotonic attribute can change, but only in some, predetermined monotonic direction.

In this case, a property type marked as applicable can later be marked as not applicable. However, a property type marked as not applicable can no longer go back to being applicable.

Because this attribute is also dynamic, the actual isApplicable values are only known when evaluated for specific complex instances. This behavior ensures that monotonic changes are deferred until evaluation. No errors are thrown; non-monotonic changes simply do not take any effect.

This attribute is Inherited

When there is no local value, the effective value of the attribute is the inherited effective value.

The first set local value must respect the monotonicity property with the inherited value.

Other characteristics

The value got by the attribute is the last set local, value, if any - a function, a constant value; or, undefined, when unset.

When set to a Nully value, the set operation is ignored.

When set and the property already has descendant properties, an error is thrown.

The default (root) isApplicable attribute value is true.

Source: javascript/web/pentaho/type/property.js, line 1296

See also:  pentaho.type.Property.Type#isRequired , pentaho.type.Complex#isApplicableOf , pentaho.type.spec.IPropertyTypeProto#isApplicable

isApplicableOn:

Evaluates the value of the isApplicable attribute of a property of this type on a given owner complex value.

Source: javascript/web/pentaho/type/property.js, line 1284

See also:  pentaho.type.Property.Type#isApplicable

isBoundary: boolean

Gets or sets whether the property is a boundary property.

A boundary property identifies the limits of the aggregate of its declaring type.

If the value type is a list type, then this property sets its lists as boundary lists.

The validity of the object with a boundary property is not affected by the validity of the property's value (or values). Also, changes within its value(s) do not bubble through it.

Boundary properties do not cause their values to hold inverse references to the property holder. This means that, in objects connected by boundary properties, only the property holders prevent their values from being garbage collected, and not the other way round. On the contrary, non-boundary properties form object aggregates that can only be garbage-collected as a whole.

Get

The default value is false.

Set

Only a root property type can set its boundary attribute. When set on a non-root property type, an error is thrown.

When set and the root property already has descendant properties, an error is thrown.

When set to a Nully value, the set operation is ignored.

Otherwise, the set value is converted to boolean, by using Boolean.

Source: javascript/web/pentaho/type/property.js, line 726

Default Value: false

isBrowsable: boolean

Gets or sets the isBrowsable attribute of this type.

Browsable types are exposed to the end user. Set this attribute to false to prevent exposing the type in a user interface.

Setting this to a Nully value causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is true.

Source: javascript/web/pentaho/type/_type.js, line 796

Overrides: pentaho.type.mixins.DiscreteDomain.Type#isBrowsable

isComplex: boolean

Gets a value that indicates if this type is a complex type.

Source: javascript/web/pentaho/type/_type.js, line 376

Overrides: pentaho.type.mixins.DiscreteDomain.Type#isComplex

isContainer: boolean

isElement: boolean

Gets a value that indicates if this type is an element type.

Source: javascript/web/pentaho/type/_type.js, line 364

Overrides: pentaho.type.mixins.DiscreteDomain.Type#isElement

isEnabled: undefined | boolean | pentaho.type.spec.PropertyDynamicAttribute.<boolean>

Gets or sets a value, or function, that indicates if properties of this type can be changed by a user, in a user interface.

A property should be set disabled whenever its value is implied/imposed somehow, and thus cannot be changed directly by the user through a user interface.

This attribute is Dynamic

When a dynamic attribute is set to a function, it can evaluate to a different value for each complex instance.

When a dynamic attribute is set to a value other than a function or a Nully value, its value is the same for every complex instance.

This attribute is Monotonic

The value of a monotonic attribute can change, but only in some, predetermined monotonic direction.

In this case, a property type marked as enabled can later be marked as not enabled. However, a property type marked as not enabled can no longer go back to being enabled.

Because this attribute is also dynamic, the actual isEnabled values are only known when evaluated for specific complex instances. This behavior ensures that monotonic changes are deferred until evaluation. No errors are thrown; non-monotonic changes simply do not take any effect.

This attribute is Inherited

When there is no local value, the effective value of the attribute is the inherited effective value.

The first set local value must respect the monotonicity property with the inherited value.

Other characteristics

The value got by the attribute is the last set local, value, if any - a function, a constant value; or, undefined, when unset.

When set to a Nully value, the set operation is ignored.

When set and the property already has descendant properties, an error is thrown.

The default (root) isEnabled attribute value is true.

Overrides: pentaho.type.mixins.DiscreteDomain.Type#isProperty

isReadOnly: boolean

Gets or sets whether the value of properties of this type can be changed.

If the value type is a list type, then this property effectively makes the list read-only.

Get

The default read-only value is the inherited read-only value.

A root property type has a default read-only value of false.

Set

When set and the property already has descendant properties, an error is thrown.

When set to a Nully value, the set operation is ignored.

Otherwise, the set value is converted to boolean, by using Boolean.

This property is monotonic. Once set to true, it can no longer be set to false.

Source: javascript/web/pentaho/type/property.js, line 661

isRequired: undefined | boolean | pentaho.type.spec.PropertyDynamicAttribute.<boolean>

Gets or sets a value that indicates if properties of this type are required.

When a property is of a required property type, it is considered invalid if its value (in a complex instance) is null; or, in the case of a list property type, it has zero elements.

Note that this attribute is taken together with the countMin attribute to determine the effective element count range of a property type.

This attribute is Dynamic

When a dynamic attribute is set to a function, it can evaluate to a different value for each complex instance.

When a dynamic attribute is set to a value other than a function or a Nully value, its value is the same for every complex instance.

This attribute is Monotonic

The value of a monotonic attribute can change, but only in some, predetermined monotonic direction.

In this case, a property type marked as not required can later be marked as required. However, a property type marked as required can no longer go back to being not required.

Because this attribute is also dynamic, the actual required values are only known when evaluated for specific complex instances. This behavior ensures that monotonic changes are deferred until evaluation. No errors are thrown; non-monotonic changes simply do not take effect.

This attribute is Inherited

When there is no local value, the effective value of the attribute is the inherited effective value.

The first set local value must respect the monotonicity property with the inherited value.

Other characteristics

The value got by the attribute is the last set local, value, if any - a function, a constant value or undefined, when unset.

When set to a Nully value, the set operation is ignored.

When set and the property already has descendant properties, an error is thrown.

The default (root) isRequired attribute value is false.

isRequiredOn:

Evaluates the value of the isRequired attribute of a property of this type on a given complex value.

This method is used to determine the effective element count range and is not intended to be used directly.

Implements:
key: string

Gets the key of the property.

The key of a property is its name.

Source: javascript/web/pentaho/type/property.js, line 204

Implements:
keyName: string

Gets the singular name of Property.Type keys.

Source: javascript/web/pentaho/type/property.js, line 194

Default Value: "name"

label: __nonEmptyString

Gets or sets the label of this type.

When set to a non-Nully and non-String value, the value is first replaced by the result of calling its toString method.

When set to an empty string or a nully value, the attribute value is reset.

When reset, the attribute assumes its default value (except on the top-root type, Instance.type, in which case it has no effect).

The default value is the inherited value.

The initial value of the attribute on the top-root type is "instance".

Source: javascript/web/pentaho/type/_type.js, line 601

Overrides: pentaho.type.mixins.DiscreteDomain.Type#label

mixins: Array.<pentaho.type.Type>

Gets or sets the mixin types that are locally mixed into this type.

Can be set to either type identifiers, instance classes or type instances and arrays thereof.

The attributes defined by the added mixin types become available for extension/configuration on this type. When extending, mixins are always applied first.

When set to a Nully value, nothing is done.

Source: javascript/web/pentaho/type/_type.js, line 545

Overrides: pentaho.type.mixins.DiscreteDomain.Type#mixins

name: __nonEmptyString

Gets or sets the name of the property type.

The name of a property type identifies it within its declaring type.

Set

This attribute must be set when defining a new property type, and cannot be changed afterwards.

When set to a non-Nully and non-String value, the value is first replaced by the result of calling its toString method.

Source: javascript/web/pentaho/type/property.js, line 261

See also:  pentaho.type.spec.IPropertyTypeProto#name

nameAlias: __nonEmptyString

Gets or sets the alias for the name of the property type.

The alias for the name of a property type is an alternative identifier for serialization purposes.

Set

This attribute can only be set when defining a new property type, and cannot be changed afterwards.

When set to a non-Nully and non-String value, the value is first replaced by the result of calling its toString method.

Source: javascript/web/pentaho/type/property.js, line 307

See also:  pentaho.type.spec.IPropertyTypeProto#nameAlias

ordinal: number

Gets or sets the ordinal associated with this type.

The ordinal is used to disambiguate the order with which a type (or an instance of it) is shown in a user interface.

Setting this to a Nully value causes this attribute to use the inherited value, except for the root type, Instance.type (which has no ancestor), where the attribute is 0.

Source: javascript/web/pentaho/type/_type.js, line 930

Overrides: pentaho.type.mixins.DiscreteDomain.Type#ordinal

See also:  pentaho.type.Type#isBrowsable , pentaho.type.Type#category

root: pentaho.type.Type

Gets the root type of this type hierarchy.

Even though the ultimate type root of types defined in this system is Instance, the system is designed to represent multiple type hierarchies, each representing concrete, more meaningful concepts.

When deriving a type from Instance, it can be marked as the root of a type hierarchy, by specifying the isRoot keyword argument to extend.

Typically, root types are immediate subtypes of Instance. However, this is not enforced and it is up to the developer to decide at what level a practical, meaningful type root arises.

For example, Value is the root of value types. However, Property, also an immediate subtype of Instance, is not considered a root type. It is the immediate subtypes of Property (each root property within a complex type) which are considered roots. This aligns with users expectations of what an attribute named root in a property type should mean.

See also:  pentaho.type.Type#isRoot , pentaho.type.Type#ancestor

shortId: __nonEmptyString

Gets the short identifier of this type.

The short identifier of a type is equal to its alias, provided it is defined. Otherwise, it is equal to the identifier.

Source: javascript/web/pentaho/type/_type.js, line 461

Overrides: pentaho.type.mixins.DiscreteDomain.Type#shortId

See also:  pentaho.type.Type#id , pentaho.type.Type#alias

sourceId: __nonEmptyString

Gets the source module identifier of this type.

The source identifier is the module identifier of the actual AMD/RequireJS module that provides the type and may be different from the identifier when an AMD package or custom mapping is configured for the module.

The source identifier is used to resolve module identifiers relative to the source module, as is the case with the pentaho.type.Type#defaultView attribute.

The source identifier of a type can only be specified when extending the ancestor type.

This attribute is not inherited.

When unspecified, defaults to the value of id.

Source: javascript/web/pentaho/type/_type.js, line 446

Overrides: pentaho.type.mixins.DiscreteDomain.Type#sourceId

See also:  pentaho.type.Type#id , pentaho.type.Type#defaultView

styleClass: __nonEmptyString

Gets or sets the CSS class associated with this type.

This attribute is typically used to associate an icon with a type.

Attempting to set to a non-string value type implicitly converts the value to a string before assignment.

An empty string or null clears the property value.

Setting to undefined, makes the property assume its default value.

The default value of a type with an id is the identifier converted to snake-case, plus special characters like \, /, _, . and spaces are converted to: a dash (). For example: "pentaho/visual/models/heatGrid" would have a default styleClass of: "pentaho-visual-ccc-heat-grid". The default value of an anonymous type is null.

Source: javascript/web/pentaho/type/_type.js, line 874

Overrides: pentaho.type.mixins.DiscreteDomain.Type#styleClass

uid: number

Gets the unique identifier of this type.

Unique type identifiers are auto-generated in each session.

Note that even anonymous types (those whose pentaho.type.Type#id is null) have a unique identifier.

This attribute is not inherited.

Source: javascript/web/pentaho/type/_type.js, line 201

Overrides: pentaho.type.mixins.DiscreteDomain.Type#uid

valueType: pentaho.type.Value.Type

Gets or sets the type of value that properties of this type can hold.

If the value type is a list type, then this property will be a list (or multiple-elements) property; otherwise, this property will be an element (or single-element) property.

Get

The default value type is the inherited value type.

A root property type has a default value type of string.

Set

When set and the property already has descendant properties, an error is thrown.

When set to a Nully value, the set operation is ignored.

Otherwise, the set value is assumed to be an spec.UTypeReference and is first resolved using this.context.get.

When set to a value type that is not a subtype of the attribute's current value type, an error is thrown.

Relation to the defaultValue attribute

When set and the defaultValue attribute is not locally set, it is set to null, blocking inheritance.

Otherwise, if it is locally set, it is checked against the new value type, and set to null, if it's not an instance of it.

Keyword arguments.

_validateValueOn(owner, value) : pentaho.type.ValidationError | Array.<pentaho.type.ValidationError>
 
Protected

Validates the given non-null value in the context of this property.

The base implementation calls _collectElementValidators to obtain the list of currently applicable element validators. Then, each element is validated against the list of collected validators.

When overriding this method, the error utilities in pentaho.type.Util can be used to help in the implementation.

Source: javascript/web/pentaho/type/property.js, line 853

Parameters:
Name Default Value Summary

See also:  pentaho.type.Type#sourceId

countRangeOn(owner) : pentaho.IRange.<number>

Evaluates the element count range of a property of this type on a given complex value.

The element count range is a conciliation of the effective value of the following attributes:

The logic can be best explained by the following simple example function:

function evaluateRange(isList, isRequiredEf, countMinEf, countMaxEf) {
  var min = countMinEf;
  var max = countMaxEf;

  if(!isList && min > 1) min = 1;
  if(!isList && max > 1) max = 1;

  if(isRequiredEf && min < 1) min = 1;

  if(max < min) max = min;

  return {min: min, max};
}

When the property is not a list property, then both the minimum and maximum values can only be either zero or one.

If isRequired is true, then the minimum must be greater than or equal to one.

The countMax value is constrained to be greater than or equal to the minimum.

Source: javascript/web/pentaho/type/property.js, line 1484

Parameters:
Name Default Value Summary
owner : pentaho.type.Complex

The complex value that owns a property of this type.

Returns:
Name Description
pentaho.IRange.<number>

The evaluated element count range.

toRef(keyArgs) : pentaho.type.spec.UTypeReference

Returns a reference to this type.

This method returns a reference to this type that is appropriate to be the value of an inline type property that is included on a specification of an instance of this type.

If an ambient specification context, currently exists, it is used to manage the serialization process. Otherwise, one is created and set as current.

When a type is not anonymous, the id is returned.

For anonymous types, a temporary, serialization-only identifier is generated. In the first occurrence in the given scope, that identifier is returned, within a full specification of the type, obtained by calling toSpecInContext.
