public class ProxyLinkedList

extends LinkedList

implements ProxyCollection

Extension of the LinkedList type that dirties the persistent/transactional field it is assigned to on modification. The need to dirty the field on any modification mandates that this class must override all mutator methods of the base type. This may lead to multiple calls to the PersistenceCapable.jdoMakeDirty(java.lang.String) for one state change if one mutator method of the base type calls another.

Constructor Detail

ProxyLinkedList

public ProxyLinkedList()

Template constructor.

ProxyLinkedList

public ProxyLinkedList(Collection contents,
                       Class elementType)

Constructor.

Parameters:

contents - The data that this collection should contain.

elementType - All elements in this collection must be instances of this type.

ProxyLinkedList

public ProxyLinkedList(Class elementType)

Constructor.

Parameters:

elementType - All elements in this collection must be instances of this type.

Method Detail

newInstance

public ProxyCollection newInstance(Class elementType,
                                   Collection contents,
                                   Comparator compare)

Description copied from interface: ProxyCollection

This method should return a new proxy of the same concrete type as the implementing class. Used by the ProxyManager factories: one template instance of each type is created for the purpose of producing new instances via this method. Overcomes the performance penalties of reflection.

Specified by:

newInstance in interface ProxyCollection

getCopy

public Collection getCopy(Collection orig)

Description copied from interface: ProxyCollection

This method should return a copy of the given collection; the copy should be of the same class as the superclass of this collection.

Specified by:

getCopy in interface ProxyCollection

getComparator

public Comparator getComparator()

Description copied from interface: ProxyCollection

Return the comparator used in this collection, or null if it is unordered or uses natural ordering.

Specified by:

getComparator in interface ProxyCollection

setOwner

public void setOwner(Object pc,
                     String fieldName)

Description copied from interface: ProxyCollection

Set the owning JDO instance of the proxy and the name of the field it is assigned to. Set to null to indicate that the proxy is no longer managed.

Specified by:

setOwner in interface ProxyCollection

getOwner

public Object getOwner()

Description copied from interface: ProxyCollection

Return the owning object.

Specified by:

getOwner in interface ProxyCollection
