PrimitiveChange

pentaho.type.changes.PrimitiveChange

The PrimitiveChange class is the abstract base class of changes that are the direct consequence of performing primitive operations on a structured value.

Primitive changes always exist in the context of a Changeset.

Example primitive changes are the Replace operation on a Complex value, and the Add and Clear operations on a List value.
