Method Summary
`EnterpriseContext (src)`	`get(java.lang.Object id)` Gets a bean instance from this cache given the identity.
`void`	`invalidateLocally(java.lang.Object id)` Remove an object from the local cache without any locking (synchronized, etc.) to avoid huge cluster-wide deadlock situations We have to unschedule passivation as well as the bean may be used on another node.

Method Detail

invalidateLocally

public void invalidateLocally(java.lang.Object id)

Remove an object from the local cache *without* any locking (synchronized, etc.) to avoid huge cluster-wide deadlock situations We have to unschedule passivation as well as the bean may be used on another node.

get

public EnterpriseContext (src)  get(java.lang.Object id)
                      throws java.rmi.RemoteException,
                             java.rmi.NoSuchObjectException

Description copied from interface: InstanceCache (src)

Gets a bean instance from this cache given the identity. This method may involve activation if the instance is not in the cache.

Implementation should have O(1) complexity.

This method is never called for stateless session beans.
