All Known Implementing Classes:: LinkConstraintsImpl

public interface LinkConstraints
extends org.eclipse.emf.ecore.EObject
extends org.eclipse.emf.ecore.EObject

A representation of the model object ' Link Constraints '. Groups constraints on the link source and target end

The following features are supported:

Method Detail

getLinkMapping


LinkMapping getLinkMapping()

Returns the value of the ' Link Mapping ' container reference. It is bidirectional and its opposite is ' Creation Constraints'. References the link mapping restricted by these constraints

Returns:: the value of the 'Link Mapping' container reference.
See Also:: GMFMapPackage.getLinkConstraints_LinkMapping(), LinkMapping.getCreationConstraints()
** Generated **
Model:: opposite="creationConstraints" resolveProxies="false" required="true" transient="false" changeable="false"

getSourceEnd


Constraint getSourceEnd()

Returns the value of the ' Source End ' containment reference. Restriction enforced by the the source end, may reference variable 'oppositeEnd' pointing to targetEnd domainMetaElement instance if available.

Returns:: the value of the 'Source End' containment reference.
See Also:: setSourceEnd(Constraint), GMFMapPackage.getLinkConstraints_SourceEnd()
** Generated **

setSourceEnd

void setSourceEnd(
Constraint value)

Sets the value of the ' Source End' containment reference.

Parameters:: value - the new value of the 'Source End' containment reference.
See Also:: getSourceEnd()
** Generated **

getTargetEnd


Constraint getTargetEnd()

Returns the value of the ' Target End ' containment reference. Restriction enforced by the the target end, may reference variable 'oppositeEnd' pointing to sourceEnd domainMetaElement instance.

Returns:: the value of the 'Target End' containment reference.
See Also:: setTargetEnd(Constraint), GMFMapPackage.getLinkConstraints_TargetEnd()
