All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>, java.util.RandomAccess, NotifyingList<E>, EList<E>, EStructuralFeature.Setting, InternalEList<E>, InternalEList.Unsettable<E>

Direct Known Subclasses:

EcoreEList.Dynamic

Enclosing class:

EcoreEList<E>

public abstract static class EcoreEList.Generic<E>
extends EcoreEList<E>

An Ecore EList with an implementation for exhibiting the appropriate feature behaviour as well as for tracking the unset state. At least one of EcoreEList.getEStructuralFeature() or EcoreEList.getFeatureID() must be specialized since each delegates to the other and without specialization this will lead to stack overflow.

public EcoreEList.Generic(int kind,
                  java.lang.Class<?> dataClass,
                  InternalEObject owner)

Method Detail

wrapperClassFor

public static java.lang.Class<?> wrapperClassFor(java.lang.Class<?> javaClass)

kind

public static int kind(EStructuralFeature eStructuralFeature)

useEquals

protected boolean useEquals()

Description copied from class: AbstractEList

Returns whether equals rather than == should be used to compare members. The default is to return true but clients can optimize performance by returning false. The performance difference is highly significant.

Overrides:

useEquals in class AbstractEList<E>

Returns:

whether equals rather than == should be used.

canContainNull

protected boolean canContainNull()

Description copied from class: NotifyingListImpl

Returns !NotifyingListImpl.hasInverse().

Overrides:

canContainNull in class NotifyingListImpl<E>

Returns:

!hasInverse.

isUnique

protected boolean isUnique()

Description copied from class: AbstractEList

Returns whether objects are constrained to appear at most once in the list. The default is to return false, but clients can override this to ensure uniqueness of contents. The performance impact is significant: operations such as add are O(n) as a result requiring uniqueness.

Overrides:

isUnique in class AbstractEList<E>

Returns:

whether objects are constrained to appear at most once in the list.

hasInverse

protected boolean hasInverse()

Description copied from class: NotifyingListImpl

Returns false.

Overrides:

hasInverse in class NotifyingListImpl<E>

Returns:

false.

hasManyInverse

protected boolean hasManyInverse()

Overrides:

hasManyInverse in class EcoreEList<E>

hasNavigableInverse

protected boolean hasNavigableInverse()

Overrides:

hasNavigableInverse in class EcoreEList<E>

isEObject

protected boolean isEObject()

Overrides:

isEObject in class EcoreEList<E>

isContainment

protected boolean isContainment()

Overrides:

isContainment in class EcoreEList<E>

hasProxies

protected boolean hasProxies()

Overrides:

hasProxies in class EcoreEList<E>

hasInstanceClass

protected boolean hasInstanceClass()

Overrides:

hasInstanceClass in class EcoreEList<E>

isInstance

protected boolean isInstance(java.lang.Object object)

Overrides:

isInstance in class EcoreEList<E>

isContainer

protected boolean isContainer()

isUnsettable

protected boolean isUnsettable()

isSet

public boolean isSet()

Description copied from class: NotifyingListImpl

Returns whether the list is considered set, i.e., whether it's not empty. A derived implementation may model this state directly.

Specified by:

isSet in interface EStructuralFeature.Setting

Specified by:

isSet in interface InternalEList.Unsettable<E>

Overrides:

isSet in class EcoreEList<E>

Returns:

whether the list is considered set.

See Also:

EObject.eIsSet(org.eclipse.emf.ecore.EStructuralFeature)

unset

public void unset()

Description copied from interface: InternalEList.Unsettable

Unsets the value held by the feature of the object.

Specified by:

unset in interface EStructuralFeature.Setting

Specified by:

unset in interface InternalEList.Unsettable<E>

Overrides:

unset in class EcoreEList<E>

See Also:

EObject.eUnset(org.eclipse.emf.ecore.EStructuralFeature)

didChange

protected void didChange()

Description copied from class: AbstractEList

Called to indicate that the data storage has been changed. This implementation does nothing; clients can use this to monitor change in the data storage.

Overrides:

didChange in class AbstractEList<E>
