Class AgentImplementation

java.lang.Object

org.cristalise.kernel.entity.ItemImplementation

org.cristalise.kernel.entity.agent.AgentImplementation

All Implemented Interfaces:

AgentOperations, ItemOperations

public class AgentImplementation
extends ItemImplementation
implements AgentOperations

Implementation of Agent, though called from the CORBA implementation ActiveEntity.

The Agent is an extension of the Item that can execute Jobs, and in doing so change the state of Item workflows, submit data to them in the form of Outcomes and run any scripts associated with those activities. In this server object, none of this specific Agent work is performed - it all must be done using the client API. The server implementation only manages the Agent's data: its roles and persistent Jobs.
