Interface DelayedProxy

All Known Implementing Classes:

DelayedArrayListProxy, DelayedHashSetProxy, DelayedLinkedHashSetProxy, DelayedLinkedListProxy, DelayedPriorityQueueProxy, DelayedTreeSetProxy, DelayedVectorProxy

public interface DelayedProxy

Implemented by proxy classes which are delay-load capable. Delay-load proxies are lazily loaded and provide some operations which allow manipulation of proxy without necessarily needing to load the proxied object.

Method Summary

Modifier and Type	Method and Description
void	closeBroker() Close the broker that is used to service this proxy.
Broker	getBroker() Get the broker that is used to service this proxy.
int	getDelayedField() Returns the expected field index even if this collection was detached.
OpenJPAStateManager	getDelayedOwner() Returns a state manager that can service this proxy even if the collection was detached.
OpenJPAStateManager	getOwnerStateManager() Returns the state manager of the owning instance.
boolean	isDetached() Returns whether the proxy is detached.
boolean	isDirectAccess() Returns whether the caller has direct-call access to the proxied object.
void	load() Load the proxy if it was delay-loaded.
void	setDirectAccess(boolean direct) Sets whether the caller has direct-call access to the proxied object.

Method Detail

load

void load()

Load the proxy if it was delay-loaded.

isDirectAccess

boolean isDirectAccess()

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.

setDirectAccess

void setDirectAccess(boolean direct)

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.

getBroker

Broker getBroker()

Get the broker that is used to service this proxy.

closeBroker

void closeBroker()

Close the broker that is used to service this proxy.

getOwnerStateManager

OpenJPAStateManager getOwnerStateManager()

Returns the state manager of the owning instance.

getDelayedOwner

OpenJPAStateManager getDelayedOwner()

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

getDelayedField

int getDelayedField()

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

isDetached

boolean isDetached()

Returns whether the proxy is detached.
