Class SpecializationType

java.lang.Object
  extended by 

org.eclipse.gmf.runtime.emf.type.core.ElementType
      extended by 
org.eclipse.gmf.runtime.emf.type.core.SpecializationType
All Implemented Interfaces:
IAdaptable, IElementType, ISpecializationType

public class SpecializationType
extends ElementType
implements ISpecializationType

Represents an application type that specializes other application types.

Specializations can contribute 'before' and 'after' advice to the editing commands associated with the application types that they specialize.

          Constructs a new instance using values from the type descriptor.
SpecializationType (java.lang.String id, java.net.URL iconURL, java.lang.String displayName, IElementType[] elementTypes, IElementMatcher matcher, IContainerDescriptor descriptor, IEditHelperAdvice editHelperAdvice)
          Constructs a new specialization type.
 
Method Summary
  IElementType[] getAllSuperTypes ()
          Gets the element supertypes for this type.
 org.eclipse.emf.ecore.EClass getEClass ()
          Gets the metaclass that is specialized by this type.
  IContainerDescriptor getEContainerDescriptor ()
          Gets the container descriptor.
  ICommand getEditCommand ( IEditCommandRequest request)
          Gets a command to edit an element of this type.
  IEditHelper getEditHelper ()
          Gets the edit helper for this element type.
  IEditHelperAdvice getEditHelperAdvice ()
          Gets my edit helper advice.
  IElementMatcher getMatcher ()

 java.lang.String[] getSpecializedTypeIds ()
          Gets the IDs of the specialized types.
  IElementType[] getSpecializedTypes ()
          Gets the element types that this type specializes.
 boolean isSpecializationOf ( IElementType type)
          Answers whether or not I am a specialization of type.

SpecializationType

public SpecializationType(
ISpecializationTypeDescriptor descriptor)
Constructs a new instance using values from the type descriptor.

Parameters:
descriptor - the specialization type descriptor
Method Detail

getEContainerDescriptor

public 
IContainerDescriptor getEContainerDescriptor()
Gets the container descriptor.

Specified by:
getEContainerDescriptor in interface ISpecializationType
Returns:
the container descriptor.

getMatcher

public 
IElementMatcher getMatcher()
Gets the element matcher.

Specified by:
getMatcher in interface ISpecializationType
Returns:
the element matcher.

getSpecializedTypes

public 
IElementType[] getSpecializedTypes()
Gets the element types that this type specializes.

Specified by:
getSpecializedTypes in interface ISpecializationType
Returns:
an array of types that are specialized by this type.

getSpecializedTypeIds

public java.lang.String[] getSpecializedTypeIds()
Gets the IDs of the specialized types.

Specified by:
getSpecializedTypeIds in interface ISpecializationType
Returns:
the IDs of the specialized types

isSpecializationOf

public boolean isSpecializationOf(
IElementType type)
Answers whether or not I am a specialization of type.

Specified by:
isSpecializationOf in interface ISpecializationType
Parameters:
type - the type to be tested
Returns:
true if I am a specialization of type, false otherwise.

getEditHelperAdvice

public 
IEditHelperAdvice getEditHelperAdvice()
Gets my edit helper advice. The advice can return 'before' or 'after' editing commands for editing elements of the types that I specialize.

Specified by:

getMetamodelType

public 
IMetamodelType getMetamodelType()
Description copied from interface: ISpecializationType
Gets the metamodel type that this type is a specialization of. This type may be a direct specialization of the metamodel type, or indirect through other specializations. It can specialize any number of other specializations, so long as they in turn all specialize the same metamodel type.
