Mapping

pentaho.visual.role. Mapping

The Mapping class holds the association between a specific visual role and the data fields of a model's current dataset, as seen internally to the visualization, by the view.

It extends the AbstractMapping class to add the mode of operation of the visual role;

AMD Module

require(["pentaho/visual/role/Mapping"], function(Mapping) { /* code goes here */ });

this, already configured, or a new value.

See also: pentaho.type.Element#configureOrCreate , pentaho.type.Value#configure

_configureProperty(propType, valueConfig)
Protected

Configures a property with a given value specification.

Execution proceeds as follows:

  1. If the property is a list property:

  2. If the config value is null, the list is cleared by calling the List#clear method;

  3. Otherwise, if the config value is distinct from the current list value, execution is delegated to the List.configure method;

  4. If the property is an element property:

  5. If either the current value or the config value are null, then the config value replaces the current value;

  6. Otherwise, execution is delegated to the Element#configureOrCreate method; if it returns an element distinct from the current value, then that value replaces the current value.

If in any of the described steps, an error is thrown if a change would result to the property's value and the property is read-only. Also, an error is thrown if the value itself would have to be mutated and its type is read-only.

Source: javascript/web/pentaho/type/Complex.js, line 483

Inherited From: pentaho.type.Complex#_configureProperty

Parameters:
Name Default Value Summary
propType : pentaho.type.PropertyType

_emit(event) : pentaho.lang.Event
Protected

Emits an unstructured event and returns it, unless it was canceled.

When this method is called, the listeners of existing registrations are notified synchronously, by priority order and then registration order, until either the event is canceled or all of the listeners have been notified.

It is safe to register or unregister to/from an event type while it is being emitted. However, changes are only taken into account in subsequent emissions.

If a listener function throws an error, the event processing is interrupted. No more registrations are processed and the error is passed to the caller.

Source: javascript/web/pentaho/lang/EventSource.js, line 269

Inherited From: pentaho.lang.EventSource#_emit

Parameters:
Name Default Value Summary
event : pentaho.lang.Event

The event object.

Returns:
Name Description
pentaho.lang.Event | null

Source: javascript/web/pentaho/lang/EventSource.js, line 325

Inherited From: pentaho.lang.EventSource#_emitGeneric

Parameters:
Name Default Value Summary
source : object

The this value of listener functions.

eventArgs : Array

The arguments of listener functions.

Optional

A predicate that indicates if the given event arguments are in a canceled state. Its this value is the value of source.

errorHandler : function
Optional

When specified with a null value, no error handling is performed and errors thrown by listeners are thrown back to this method's caller. When unspecified or specified as undefined, defaults to a function that simply logs the listener errors, and lets execution continue to the following listeners. The function arguments are: the error, the eventArgs, the event type and the event phase. Its this value is the value of source.

interceptor : function
Optional
null

A function which is called for each event listener function, with the arguments listener, source, eventArgs and the index of the listener.

Returns:
Name Description
boolean

false when the event is canceled; true, otherwise.

_emitGenericAllAsync(source, eventArgs, type, phase, keyArgs) : Promise.<object>
Protected

Emits an event asynchronously, given an arbitrary payload object, its type and phase, and succeeding if every listener succeeds.

Listeners are called in parallel.

Returns a promise that is fulfilled or rejected with the event payload object. If any listener throws or rejects, the returned promise is rejected as well.

Source: javascript/web/pentaho/lang/EventSource.js, line 454

Inherited From: pentaho.lang.EventSource#_emitGenericAllAsync

Parameters:
Name Default Value Summary
source : object

The this value of listener functions.

Parameters:
Name Default Value Summary
isCanceled : function
Optional

A predicate that indicates if the given event arguments are in a canceled state. Its this value is the value of source.

getCancellationReason : function
Optional

A function that given the event arguments returns its a cancellation reason, usually an Error. Its this value is the value of source.

errorHandler : function
Optional

When specified with a null value, no error handling is performed. Errors thrown by, or promises rejected by, any listeners cause the whole event to be rejected.

When unspecified or specified as undefined, defaults to a function that simply logs any listener errors, yet always succeeding.

The function arguments are: the error, the event, the event type and the event phase.

Returns:
Name Description
Promise.<object>

A promise. When fulfilled, it is with the value undefined. When rejected due to a thrown error, the rejection reason is that error. When explicitly rejected by the error handler, the given rejection reason is preserved. When rejected due to a cancellation, the rejection reason is the cancellation reason, if any.

This method considers configuration to not be possible in the following situations:

  1. this instance is of a read-only type;
  2. config is of an isEntity type and is not equals to this value;
  3. config is not an instance of an isEntity type but is an instance of Value and its constructor is not the same as this;
  4. config is not an instance of Value - it is a specification and: 4.1. it contains an inline type property, _, identifying a different type than that of this instance; 4.2. this instance is of an isEntity type and config contains key properties that reference another entity.

If configuration is considered possible, the actual configuration is delegated to the configure method.

This method checks if the given value is identical to this one. Otherwise, if not Nully and has the same constructor, execution is delegated to this value's _equals method.

Source: javascript/web/pentaho/type/Value.js, line 116

Inherited From: pentaho.type.Value#equals

Parameters:
Name Default Value Summary
other : pentaho.type.Value

A value to test for equality.

Returns:
Name Description
boolean

true if the given value is equal to this one; or, false, otherwise.

Methods that are overridden are accessible through this.base.

This object is extended, but its class doesn't change.

Source: javascript/web/pentaho/lang/Base.js, line 1040

Inherited From: pentaho.lang.Base#extend

Parameters:
Name Default Value Summary
source : object

The instance specification.

keyArgs : object
Optional

The keyword arguments.

Parameters:
Name Default Value Summary
exclude : object
Optional

A map of property names to exclude from source.

Returns:
Name Description
object

This object.

get(name, sloppy) : pentaho.type.Value | Nully

Gets the value of a property.

If the specified property is not defined and sloppy is true, undefined is returned.

A list property always has a non-null value, possibly an empty list, but never null. An element property can have a null value.

Source: javascript/web/pentaho/type/Complex.js, line 248

Inherited From: pentaho.type.Complex#get

Parameters:
Name Default Value Summary
name : string | pentaho.type.PropertyType
Optional

The property name or type object.

sloppy : boolean
Optional
false

Indicates if an error is thrown if the specified property is not defined.

Returns:
Name Description
pentaho.type.Value | Nully

The value of the property, or a Nully value.

Throws:
Name Description
pentaho.lang.ArgumentInvalidError

When sloppy is false and a property with name name is not defined.

See also: pentaho.type.Complex#getv , pentaho.type.Complex#getf

getf(name, sloppy) : string

Gets the string representation of the value of a property.

This method reads the value of the property by calling Complex#get.

When the latter returns a Nully value, "" is returned. Otherwise, the result of the value's toString() method is returned.

For a Simple type, this corresponds to returning its formatted attribute, when it is not null. For Complex and List types, varies with the implementation.

Source: javascript/web/pentaho/type/Complex.js, line 339

Inherited From: pentaho.type.Complex#getf

Parameters:
Name Default Value Summary
name : string | pentaho.type.PropertyType

The property name or type object.

sloppy : boolean
Optional
false

Indicates if an error is thrown if the specified property is not defined.

Returns:
Name Description
string

The string representation of the value, or "".

Throws:
Name Description
pentaho.lang.ArgumentInvalidError

When sloppy is false and a property with name name is not defined.

See also: pentaho.type.Complex#get , pentaho.type.Complex#getv

getv(name, sloppy) : * | pentaho.type.Complex | pentaho.type.List | Nully

Gets the primitive value of the value of a property.

This method reads the value of the property by calling Complex#get.

When the latter does not return a Nully value, the result of the value's valueOf() method is returned.

For a Simple type, this corresponds to returning its value attribute. For Complex and List types, this corresponds to the value itself.

Implements:
off(typeOrHandle, observer)

Removes one registration given its handle, or all registrations of a given event type (or types) and observer (or listener function).

To remove an event registration, it is sufficient to call the dispose method of the registration handle returned by on, upon registration. Alternatively, as a convenience syntax, the registration handle can be passed as the single argument to this method.

It is safe to unregister from an event type while it is being emitted. However, any registrations removed during the current emission will still execute.

Specifying an event registration handle that has already been disposed of has no effect. Specifying an event type and observer (or listener function) that have no registrations has no effect.

Source: doc-js/pentaho/lang/IEventSource.jsdoc, line 131

Inherited From: pentaho.lang.EventSource#off

Parameters:
Name Default Value Summary
typeOrHandle : nonEmptyString | Array.<nonEmptyString> | pentaho.lang.IEventRegistrationHandle

The type or types of events, or an event registration handle to dispose of. When a string, it can be a comma-separated list of event types.

observer : pentaho.lang.IEventObserver | pentaho.lang.EventListener | pentaho.lang.EventListenerAsync

The event observer (or listener function). Required when typeOrHandle is not an event registration handle; ignored, otherwise.

See also: pentaho.lang.IEventSource#on

Implements:
on(type, observer, keyArgs) : pentaho.lang.IEventRegistrationHandle

Registers an observer (or listener function) for an event(s) of a given type(s).

Optionally, a listening priority may be specified to adjust the order by which an observer is notified, relative to other listeners.

Note that if an observer is registered more than once to the same event type, a new registration is created each time and its listeners will be called once per registration.

It is safe to register for an event type while it is being emitted. However, new registrations are only taken into account in subsequent emissions.

When type represents multiple event types, the returned event registration handle is a composite registration for all of the event types.

This method is compatible with the dojo/on API.

Source: doc-js/pentaho/lang/IEventSource.jsdoc, line 90

Inherited From: pentaho.lang.EventSource#on

Parameters:
Name Default Value Summary
type : nonEmptyString | Array.<nonEmptyString>

The type or types of events. When a string, it can be a comma-separated list of event types.

observer : pentaho.lang.IEventObserver | pentaho.lang.EventListener | pentaho.lang.EventListenerAsync

The event observer (or listener function).

keyArgs : object
Optional

Keyword arguments.

Parameters:
Name Default Value Summary
priority : number
Optional
0

The listening priority. Higher priority observers are notified of an event before any lower priority observers. The priority can be set to -Infinity or Infinity. In case two observers are assigned the same priority, the registration order determines which is notified first.

Returns:
Name Description
pentaho.lang.IEventRegistrationHandle

An event registration handle that can be used for later removal.

See also: pentaho.lang.IEventSource#off

set(name, valueSpec)

Sets the value of a property.

The value of List properties is automatically created, when complex instance is constructed, and is never replaced by another list value. However, its contents can be modified. On the other hand, for element properties, their value can be replaced.

Execution proceeds as follows:

  1. If the property is a list property:

  2. If value is Nully, the list is cleared by calling the List#clear method; however, if the property is read-only and the list has any elements, an error is thrown instead;

  3. Otherwise, if value is distinct from the current list value, an elements list is extracted from the given value (see ListType#_normalizeInstanceSpec) and execution is delegated to the List#set method; likewise, if changes to the list would result and the property is read-only, an error is thrown;

  4. If the property is an element property:

  5. If value is Nully, the property's default value, if any, is evaluated and value is set to it; the property's new defaulted status will be true.

  6. Otherwise, if the specified value is not Nully, the property's new defaulted status will be false.

  7. If value is not equal to the current value and/or the property's defaulted status changes:

    1. If the property is read-only, an error is thrown.
    2. Otherwise, the current value and the defaulted status are replaced by the new ones.
    3. A change action is executed, resulting in the change phase events init, will and finally being emitted.
  8. Otherwise, if value and the defaulted status do not change, nothing is done.

In both cases, of element and list properties, when the given value(s) is a specification, it is first constructed, before any comparison with the current value(s) is performed.

Contrast this behavior with that of the configure method, in which specifications aren't considered to have an identity, a priori. Only if these explicitly identify an entity or value which is incompatible with the current value are they assumed to represent a new value that needs to be constructed.

For element properties, specifications are constructed having as default type the valueType of the property.

For list properties, each element's specification is constructed having as default type the elementType of the property's valueType.

toJSON() : JsonValue

Creates a top-level JSON specification that describes this instance.

Attributes which do not have a JSON-compatible specification are omitted. Specifically, for inline types, attributes with a function value are not supported.

This method simply calls pentaho.type.Instance#toSpec with argument keyArgs.isJson as true and exists for seamless integration with JavaScript's JSON.stringify method.

Source: javascript/web/pentaho/type/Instance.js, line 198

Inherited From: pentaho.type.Instance#toJSON

Returns:
Name Description
JsonValue | null

A JSON-compatible specification.

See also: pentaho.type.Instance#toSpec

Implements:
toSpec(keyArgs) : pentaho.type.spec.Instance

Creates a specification that describes this value.

If an ambient specification context, currently exists, it is used to manage the serialization process. Otherwise, one is created and set as current. Then, the actual work is delegated to pentaho.type.Instance#toSpecInContext.

Source: javascript/web/pentaho/type/Value.js, line 272

Inherited From: pentaho.type.Value#toSpec

Parameters:
Name Default Value Summary
keyArgs : object
Optional

The keyword arguments object. Passed to every value and type serialized within this scope.

Please see the documentation of value subclasses for information on additional, supported keyword arguments.

Parameters:
Name Default Value Summary
isJson : boolean
Optional
false

Generates a JSON-compatible specification. Attributes which do not have a JSON-compatible specification are omitted.

declaredType : pentaho.type.Type
Optional

The base type of this value's storage location. If the value does not have this exact type, its inline type property must be included in the specification. Otherwise, it can be omitted. When unspecified, the inline type property is only included if forceType is true.

forceType : boolean
Optional
false

Forces inclusion of the inline type property, _, in the specification.

omitFormatted : boolean
Optional
false

Omits the formatted value on Simple values' specifications.

preferPropertyArray : boolean
Optional
false

Indicates that, if possible, array form is used for Complex values' specifications.

The array form of a complex value cannot be used when its type must be inlined.

includeDefaults : boolean
Optional
false

When true, all of the properties of Complex values are serialized. When false, the default, only properties whose value is different from their default value are serialized.

Only applies to complex values that are serialized in object form. In array form, all of the properties of complex values are serialized independently of their value.

omitProps : object
Optional

An object whose own property names with a truthy value are the names of the properties of the current complex type to omit from the serialization.

Only applies when a complex is output in object form. In array form, all properties are output whatever their value.

This argument only applies to complex values and is not passed through to the values of their properties.

Returns:
Name Description
pentaho.type.spec.Instance | null

A specification of this value.

toSpecInContext(keyArgs) : *

Creates a specification that describes this instance.

Source: javascript/web/pentaho/type/Instance.js, line 178

Inherited From: pentaho.type.Instance#toSpecInContext

Parameters:
Name Default Value Summary
keyArgs : object
Optional

The keyword arguments' object. Passed to every instance and type serialized within this scope.

Please see the documentation of subclasses for information on additional, supported keyword arguments.

Returns:
Name Description
*

A specification of this instance.
