Interface BoundContext<S>

Type Parameters:

S - the type of the external instance storage

All Superinterfaces:

AlterableContext, Context

All Known Subinterfaces:

BoundConversationContext, BoundRequestContext, BoundSessionContext, EjbRequestContext, HttpConversationContext, HttpRequestContext, HttpSessionContext

public interface BoundContext<S>
extends AlterableContext

Allows a thread-based context to be bound to some external instance storage (such as an HttpSession).

A context may be detachable in which case a call to ManagedContext.invalidate() will detach the context from it's associated storage. A detached context is still usable (instances may be added or removed) however changes will not be written through to the underlying data store.

Normally, a detachable context will have it's underlying bean store attached on a call to ManagedContext.activate() and detached on a call to ManagedContext.deactivate() however a subtype of BoundContext may change this behavior.

If you call associate(Object) you must ensure that you call dissociate(Object) in all cases, otherwise you risk memory leaks.

Method Detail

associate

boolean associate(S storage)

Associate the context with the storage (for this thread). Once associate(Object) has been called, further calls to associate(Object) will be ignored, until the context has been subsequently dissociate(Object) from the storage.

Parameters:

storage - the external storage

Returns:

true if the storage was attached, otherwise false

dissociate

boolean dissociate(S storage)

Dissociate the context from the storage (for this thread). The context will only dissociate from the same storage it associated with.

Parameters:

storage - the external storage

Returns:
