java.lang.Object

oracle.toplink.essentials.internal.queryframework.ContainerPolicy

oracle.toplink.essentials.internal.queryframework.InterfaceContainerPolicy

oracle.toplink.essentials.internal.queryframework.CollectionContainerPolicy

oracle.toplink.essentials.internal.queryframework.ListContainerPolicy

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

OrderedListContainerPolicy

public class ListContainerPolicy
extends CollectionContainerPolicy

Purpose: A ListContainerPolicy is ContainerPolicy whose container class implements the List interface. This signifies that the collection has order

Responsibilities: Provide the functionality to operate on an instance of a List.

Constructors

Constructor and Description
ListContainerPolicy() INTERNAL: Construct a new policy.
ListContainerPolicy(java.lang.Class containerClass) INTERNAL: Construct a new policy for the specified class.
ListContainerPolicy(java.lang.String containerClassName) INTERNAL: Construct a new policy for the specified class name.

Method Summary

Modifier and Type	Method and Description
boolean	hasOrder() INTERNAL: Returns true if the collection has order.
boolean	isListPolicy() INTERNAL: Returns true if this is a ListContainerPolicy.
boolean	isValidContainer(java.lang.Object container) INTERNAL: Validate the container type.
void	recordAddToCollectionInChangeRecord(ObjectChangeSet changeSetToAdd, CollectionChangeRecord collectionChangeRecord) This method is used to bridge the behaviour between Attribute Change Tracking and deferred change tracking with respect to adding the same instance multiple times.
void	recordRemoveFromCollectionInChangeRecord(ObjectChangeSet changeSetToRemove, CollectionChangeRecord collectionChangeRecord) This method is used to bridge the behaviour between Attribute Change Tracking and deferred change tracking with respect to adding the same instance multiple times.

Constructor Detail

ListContainerPolicy

public ListContainerPolicy()

INTERNAL: Construct a new policy.

ListContainerPolicy

public ListContainerPolicy(java.lang.Class containerClass)

INTERNAL: Construct a new policy for the specified class.

ListContainerPolicy

public ListContainerPolicy(java.lang.String containerClassName)

INTERNAL: Construct a new policy for the specified class name.

Method Detail

hasOrder

public boolean hasOrder()

INTERNAL: Returns true if the collection has order.

Overrides:

hasOrder in class CollectionContainerPolicy

isListPolicy

public boolean isListPolicy()

INTERNAL: Returns true if this is a ListContainerPolicy.

Overrides:

isListPolicy in class ContainerPolicy

isValidContainer

public boolean isValidContainer(java.lang.Object container)

INTERNAL: Validate the container type.

Overrides:

isValidContainer in class CollectionContainerPolicy

CollectionContainerPolicy.isValidContainer(Object), MapContainerPolicy.isValidContainer(Object)

recordAddToCollectionInChangeRecord

public void recordAddToCollectionInChangeRecord(ObjectChangeSet changeSetToAdd,
                                                CollectionChangeRecord collectionChangeRecord)

This method is used to bridge the behaviour between Attribute Change Tracking and deferred change tracking with respect to adding the same instance multiple times. Each containerplicy type will implement specific behaviour for the collection type it is wrapping. These methods are only valid for collections containing object references.

Overrides:

recordAddToCollectionInChangeRecord in class ContainerPolicy

recordRemoveFromCollectionInChangeRecord

public void recordRemoveFromCollectionInChangeRecord(ObjectChangeSet changeSetToRemove,
                                                     CollectionChangeRecord collectionChangeRecord)

This method is used to bridge the behaviour between Attribute Change Tracking and deferred change tracking with respect to adding the same instance multiple times. Each container policy type will implement specific behaviour for the collection type it is wrapping. These methods are only valid for collections containing object references.

Overrides:

recordRemoveFromCollectionInChangeRecord in class ContainerPolicy
