Examples of javax.slee.ActivityContextInterface

javax.slee.ActivityContextInterface
The ActivityContextInterface interface provides an SBB object with a Java interface to an Activity Context.
An SBB may define shareable state to be stored in the Activity Context by extending the ActivityContextInterface interface and adding CMP-style accessor methods for the state attributes. State can be shared either between SBB objects of the same SBB type, or between all SBB objects of any SBB type. The configuration of an SBB's Activity Context Interface is declared in the SBB's deployment descriptor.
