All Implemented Interfaces:

Serializable, Cloneable, Iterable, Collection, List, RandomAccess, Proxy, ProxyCollection

public class ProxyVector
extends Vector
implements ProxyCollection

Extension of the Vector 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 dirty for one state change if one mutator method of the base type calls another.

public ProxyVector()

ProxyVector

public ProxyVector(Class elementType,
                   boolean trackChanges,
                   OpenJPAConfiguration conf)

Method Detail

setOwner

public void setOwner(OpenJPAStateManager sm,
                     int field)

Description copied from interface: Proxy

Reset the state of the proxy, and set the owning 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 Proxy

getOwner

public OpenJPAStateManager getOwner()

Description copied from interface: Proxy

Return the owning object.

Specified by:

getOwner in interface Proxy

getOwnerField

public int getOwnerField()

Description copied from interface: Proxy

Return the owning field index.

Specified by:

getOwnerField in interface Proxy

getChangeTracker

public ChangeTracker getChangeTracker()

Description copied from interface: Proxy

Return the change tracker for this proxy, or null if none.

Specified by:

getChangeTracker in interface Proxy

copy

public Object copy(Object orig)

Description copied from interface: Proxy

Return an unproxied copy of the given instance. This method is used by proxy managers to create backup values for use in rollback.

Specified by:

copy in interface Proxy

newInstance

public ProxyCollection newInstance(Class elementType,
                                   Comparator compare,
                                   boolean trackChanges,
                                   OpenJPAConfiguration conf)

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
