Class EStructuralFeatureValueGetter

java.lang.Object
  org.eclipse.emf.query.conditions.eobjects.structuralfeatures.EStructuralFeatureValueGetter

All Implemented Interfaces:

IEStructuralFeatureValueGetter

public class EStructuralFeatureValueGetter
extends Object
implements IEStructuralFeatureValueGetter

A default implementation of the IEStructuralFeatureValueGetter interface. It behaves as though the argument eObject passed to it require no preparation or modification before or after invoking its methods and therefore it accesses the methods of the argument eObject passed to it directly.

Constructor Summary

EStructuralFeatureValueGetter()
Deprecated. Use the singleton provided by getInstance().

Method Summary

List<EObject>	eContents(EObject eObject, EObjectCondition filterCondition) Extract the contained EObjects of the argument eObject. and return them as a list.
Object	eGet(EObject eObject, EStructuralFeature eFeature, boolean resolve) An EStructuralFeature's value getter.
static IEStructuralFeatureValueGetter	getInstance()
EObject	resolve(EObject eObject) Does nothing.

eContents

public List<EObject> eContents(EObject eObject,
                               EObjectCondition filterCondition)

Description copied from interface: IEStructuralFeatureValueGetter

Extract the contained EObjects of the argument eObject. and return them as a list. It uses an -optional- EObjectCondition as a filtering condition of the content list where only those children EObjects that satisfy the filterCondition will be returned to the caller

Specified by:

eContents in interface IEStructuralFeatureValueGetter

Parameters:

eObject - The EObject to extract children from

filterCondition - The EObjectCondition to apply on the children in order to remove out those that don't satisfy it. It could be null.

Returns:

List The list of children of the argument eObject.

eGet

public Object eGet(EObject eObject,
                   EStructuralFeature eFeature,
                   boolean resolve)

Description copied from interface: IEStructuralFeatureValueGetter

An EStructuralFeature's value getter.

Specified by:

eGet in interface IEStructuralFeatureValueGetter

Parameters:

eObject - The context eObject whose EStructuralFeature's value is to be returned

eFeature - The EStructuralFeature whose value is to be returned

resolve - A boolean flag indicating whether to resolve or not when extracting the value.

Returns:

Object the value held by the eFeature argument

resolve

public EObject resolve(EObject eObject)

Does nothing. Returns the same eObject passed.

Specified by:

resolve in interface IEStructuralFeatureValueGetter

Parameters:

eObject - The EObject to be prepared

Returns:

EObject the prepared EObject
