Constructor Detail

EObjectStructuralFeatureCondition

public EObjectStructuralFeatureCondition(PruneHandler pruneHandler,
                                         EStructuralFeature feature)

A constructor, initializes the EObjectStructuralFeatureCondition with basic values.

Parameters:

pruneHandler - The PruneHandler to consult when pruning

feature - The EStructuralFeature used for evaluation by this EObjectStructuralFeatureCondition

Method Detail

isSatisfied

public boolean isSatisfied(EObject eObject)

Answers whether the argument eObject has the EStructuralFeature used in initialization of this EObjectStructuralFeatureCondition

Specified by:

isSatisfied in class EObjectCondition

Parameters:

eObject - the EObject to check

Returns:

boolean true if the argument eObject satisfies this EObjectCondition

getFeature

protected final EStructuralFeature getFeature()

A getter for the EStructuralFeature used in initialization of this EObjectStructuralFeatureCondition

Returns:

EStructuralFeature the feature used in initialization of this EObjectStructuralFeatureCondition

getFeatures

protected List<? extends EStructuralFeature> getFeatures(EClass eClass)

Returns the list of all EStructuralFeatures of the given EClass that are consequently to be used for testing and evaluation of this condition object

Parameters:

eClass - the Eclass from which to get all the EStructuralFeatures to be used for testing and evaluation of this condition object

Returns:

List a list of the all the EStructuralFeatures from the argument EClass and are consequently to be used for testing and evaluation of this condition object
