Examples of org.apache.qpid.qmf2.console.Agent

org.apache.qpid.qmf2.console.QmfConsoleData
Local representation (proxy) of a remote Agent.
This class holds some state that relates to the Agent and in addition some methods may be called on the agent. destroy(), invokeMethod() and refresh() are actually called by a proxy class AgentProxy. AgentProxy is actually an interface that is implemented by Console (as that's where all the JMS stuff is), we use this approach to avoid introducing a circular dependency between Agent and Console.
The Console application maintains a list of all known remote Agents. Each Agent is represented by an instance of the Agent class:
The following diagram illustrates the interactions between the Console, AgentProxy and the client side Agent representation.
