public class DelayedVectorProxy
extends Vector
implements ProxyCollection, DelayedProxy

Vector 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 Detail

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

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

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

isDirectAccess

public boolean isDirectAccess()

Description copied from interface: DelayedProxy

Returns 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:

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

getBrokerFactory

public BrokerFactory getBrokerFactory()

load

public void load()

Description copied from interface: DelayedProxy

Load the proxy if it was delay-loaded.

Specified by:

load in interface DelayedProxy

public void closeBroker()

Description copied from interface: DelayedProxy

Close the broker that is used to service this proxy.

Specified by:

closeBroker in interface DelayedProxy

getOwnerStateManager

public OpenJPAStateManager getOwnerStateManager()

Description copied from interface: DelayedProxy

Returns the state manager of the owning instance.

Specified by:

getOwnerStateManager in interface DelayedProxy
