public class EObjectReferencerCondition
extends EObjectCondition

An EObjectCondition subclass that tests if a given EObject references another EObject.

For the purposes of this condition, a container or containment EReference is not considered a "reference."

EObjectReferencerCondition

public EObjectReferencerCondition(EObject referencedEObject,
                                  IEStructuralFeatureValueGetter eStructuralFeatureValueGetter)

A constructor, initializes this EObjectReferencerCondition with the passed arguments. It default to using PruneHandler.NEVER

Parameters:

referencedEObject - The EObject to search for

eStructuralFeatureValueGetter - the referencing EReference value getter

EObjectReferencerCondition

public EObjectReferencerCondition(EObject referencedEObject)

A constructor, initializes this EObjectReferencerCondition with the passed arguments. It default to using PruneHandler.NEVER

The default EStructuralFeatureValueGetter will be used when accessing the values of the EReferences.

Parameters:

referencedEObject - The EObject to search for

EObjectReferencerCondition

public EObjectReferencerCondition(EObject referencedEObject,
                                  IEStructuralFeatureValueGetter eStructuralFeatureValueGetter,
                                  PruneHandler pruneHandler)

* A constructor, initializes this EObjectReferencerCondition with the passed arguments. It default to using PruneHandler.NEVER

Parameters:

referencedEObject - The EObject to search for

eStructuralFeatureValueGetter - the referencing EReference value getter

pruneHandler - The PruneHandler

Method Detail

isSatisfied

public boolean isSatisfied(EObject eObject)

Checks the argument eObject if it has any non-containment EReference whose value is equal to/contains the referencedEObject that this EObjectReferencerCondition is initialized with.

Specified by:

isSatisfied in class EObjectCondition

Parameters:

eObject - the EObject to check

Returns:

boolean true if the argument eObject satisfies this EObjectCondition
