Interface SegmentIdeDescriptor

All Known Implementing Classes:

FeatureSegmentIdeDescriptor, IndexSegmentIdeDescriptor, MappingSegmentIdeDescriptor, MultiSegmentIdeDescriptor

public interface SegmentIdeDescriptor

A SegmentIdeDescriptor provides information about one type of VDomainModelReferenceSegment relevant to the IDE tooling. For instance, this information is needed by the CreateSegmentDmrWizard to properly create DMRs with different segment types.

Method Summary

Modifier and Type	Method	Description
EStructuralFeatureSelectionValidator	getEStructuralFeatureSelectionValidator()	Returns an EStructuralFeatureSelectionValidator that determines whether an EStructuralFeature is a valid reference path part for the described segment type.
ReferenceTypeResolver	getReferenceTypeResolver()	Returns a ReferenceTypeResolver that resolves the root EClass for the next reference path segment from an EReference.
org.eclipse.emf.ecore.EClass	getSegmentType()	Returns the EClass of the segment type that is described by this SegmentIdeDescriptor.
boolean	isAllowedAsLastElementInPath()	Defines whether the described segment can be the last element of a reference path.
boolean	isAvailableInIde()	Defines whether the described segment type may be created by users.
boolean	isLastElementInPath()	Defines whether the described segment may appear in the middle of a reference path or if the segment is only allowed to be at the end of a path.

Method Detail

getSegmentType

org.eclipse.emf.ecore.EClass getSegmentType()

Returns the EClass of the segment type that is described by this SegmentIdeDescriptor.

Returns:

The segment's EClass

isAvailableInIde

boolean isAvailableInIde()

Defines whether the described segment type may be created by users.

Returns:

true if users may create the type, false otherwise

isLastElementInPath

boolean isLastElementInPath()

Defines whether the described segment may appear in the middle of a reference path or if the segment is only allowed to be at the end of a path.

Returns:

true if the segment must only be at the end of a path, false otherwise

isAllowedAsLastElementInPath

boolean isAllowedAsLastElementInPath()

Defines whether the described segment can be the last element of a reference path.

Returns:

true if the segment can be the last element of a reference path, false otherwise

getEStructuralFeatureSelectionValidator

EStructuralFeatureSelectionValidator getEStructuralFeatureSelectionValidator()

Returns an EStructuralFeatureSelectionValidator that determines whether an EStructuralFeature is a valid reference path part for the described segment type. E.g. an index segment needs a multi reference or attribute.

Returns:

The EStructuralFeatureSelectionValidator

getReferenceTypeResolver

ReferenceTypeResolver getReferenceTypeResolver()

Returns a ReferenceTypeResolver that resolves the root EClass for the next reference path segment from an EReference.

Returns:

The ReferenceTypeResolver
