public class DelayedLinkedListProxy
extends LinkedList
implements ProxyCollection, DelayedProxy

LinkedList proxy with delay loading capability. Allows non-indexed add and remove operations to occur on an unloaded collection. Operations that require a load will trigger a load.

Method Details

setOwner

public void setOwner(OpenJPAStateManager paramOpenJPAStateManager,
 int paramInt)

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

setChangeTracker

protected void setChangeTracker(CollectionChangeTracker ct)

copy

public Object copy(Object paramObject)

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

getElementType

public Class getElementType()

Description copied from interface: ProxyCollection

The collection element type.

Specified by:

getElementType in interface ProxyCollection

setElementType

protected void setElementType(Class<?> elemType)

newInstance

public ProxyCollection newInstance(Class paramClass,
 Comparator paramComparator,
 boolean paramBoolean1,
 boolean paramBoolean2)

Description copied from interface: ProxyCollection

Create a new instance of this proxy type.

Specified by:

newInstance in interface ProxyCollection

getDelayedField

public int getDelayedField()

Description copied from interface: DelayedProxy

Returns the expected field index even if this collection was detached.

Specified by:

getDelayedField in interface DelayedProxy

getDelayedOwner

public OpenJPAStateManager getDelayedOwner()

Description copied from interface: DelayedProxy

Returns a state manager that can service this proxy even if the collection was detached.

Specified by:

getDelayedOwner in interface DelayedProxy

Specified by:

isDirectAccess in interface DelayedProxy

setDirectAccess

public void setDirectAccess(boolean direct)

Description copied from interface: DelayedProxy

Sets whether the caller has direct-call access to the proxied object. Direct access allows calls to be made on the object without triggering a load or proxy state tracking callbacks.

Specified by:

setDirectAccess in interface DelayedProxy
