Method Detail

addInto	back to summary
public boolean addInto(Object element, Object container, ABSTRACT_SESSION session) INTERNAL: Add element to container. This is used to add to a collection independent of JDK 1.1 and 1.2. The session may be required to wrap for the wrapper policy. Return whether the container changed

addInto	back to summary
public boolean addInto(Object key, Object element, Object container, ABSTRACT_SESSION session) INTERNAL: Add element to container. This is used to add to a collection independent of type. The session may be required to wrap for the wrapper policy. Return whether the container changed.

clear	back to summary
public void clear(Object container) INTERNAL: Remove all the elements from the specified container. Valid only for certain subclasses.

containerInstance	back to summary
public Object containerInstance() INTERNAL: Return an instance of the container class. Null should never be returned. A ValidationException is thrown on error.

containerInstance	back to summary
public Object containerInstance(int initialCapacity) INTERNAL: Return an instance of the container class with the specified initial capacity. Null should never be returned. A ValidationException is thrown on error.

contains	back to summary
public boolean contains(Object element, Object container, ABSTRACT_SESSION session) INTERNAL: Check if the object is contained in the collection. This is used to check contains in a collection independent of JDK 1.1 and 1.2. The session may be required to unwrap for the wrapper policy.

hasNext back to summary

hasNext	back to summary
public boolean hasNext(Object iterator) INTERNAL: Return whether the iterator has more objects. The iterator is the one returned from #iteratorFor(). Valid for some subclasses only. See Also `ContainerPolicy#iteratorFor(Object)`

public boolean hasNext(Object iterator)

INTERNAL: Return whether the iterator has more objects. The iterator is the one returned from #iteratorFor(). Valid for some subclasses only.

See Also: ContainerPolicy#iteratorFor(Object)

isEmpty	back to summary
public boolean isEmpty(Object container) INTERNAL: Return whether the container is empty.

isListPolicy	back to summary
public boolean isListPolicy()

iteratorFor back to summary

iteratorFor	back to summary
public Object iteratorFor(Object container) INTERNAL: Return an iterator for the given container. This iterator can then be used as a parameter to #hasNext() and #next(). See Also `ContainerPolicy#hasNext(Object)`, `ContainerPolicy#next(Object, org.eclipse.persistence.internal.sessions.AbstractSession)`

public Object iteratorFor(Object container)

INTERNAL: Return an iterator for the given container. This iterator can then be used as a parameter to #hasNext() and #next().

See Also: ContainerPolicy#hasNext(Object), ContainerPolicy#next(Object, org.eclipse.persistence.internal.sessions.AbstractSession)

next	back to summary
public Object next(Object iterator, ABSTRACT_SESSION session) INTERNAL: Return the next object from the iterator. This is used to stream over a collection independent of JDK 1.1 and 1.2. The session may be required to unwrap for the wrapper policy.

nextEntry back to summary

nextEntry	back to summary
public Object nextEntry(Object iterator) INTERNAL: Return the next object on the queue. The iterator is the one returned from #iteratorFor(). In the case of a Map, this will return a MapEntry to allow use of the key See Also `ContainerPolicy#iteratorFor(Object)`, `MapContainerPolicy#unwrapIteratorResult(Object)`

public Object nextEntry(Object iterator)

INTERNAL: Return the next object on the queue. The iterator is the one returned from #iteratorFor(). In the case of a Map, this will return a MapEntry to allow use of the key

See Also: ContainerPolicy#iteratorFor(Object), MapContainerPolicy#unwrapIteratorResult(Object)

nextEntry back to summary

nextEntry	back to summary
public Object nextEntry(Object iterator, ABSTRACT_SESSION session) INTERNAL: Return the next object on the queue. The iterator is the one returned from #iteratorFor(). In the case of a Map, this will return a MapEntry to allow use of the key See Also `ContainerPolicy#iteratorFor(Object)`, `MapContainerPolicy#unwrapIteratorResult(Object)`

public Object nextEntry(Object iterator, ABSTRACT_SESSION session)

INTERNAL: Return the next object on the queue. The iterator is the one returned from #iteratorFor(). In the case of a Map, this will return a MapEntry to allow use of the key

See Also: ContainerPolicy#iteratorFor(Object), MapContainerPolicy#unwrapIteratorResult(Object)

removeFrom	back to summary
public boolean removeFrom(Object element, Object container, ABSTRACT_SESSION session) INTERNAL: Remove the object from the collection. This is used to remove from a collection independent of JDK 1.1 and 1.2. The session may be required to unwrap for the wrapper policy.

sizeFor	back to summary
public int sizeFor(Object container) INTERNAL: Return the size of container.

vectorFor	back to summary
public Vector<E> vectorFor(Object container, ABSTRACT_SESSION session) INTERNAL: Return a Vector populated with the contents of container. Added for bug 2766379, must implement a version of vectorFor that handles wrapped objects.

public Interface CoreContainerPolicy<ABSTRACT_SESSION extends CoreAbstractSession>
