Method Detail

createClientAgent

public ClientAgentRemote createClientAgent(java.lang.String agentName)
                                    throws java.lang.Exception

Creates a new client agent with the given name. Instantiates ClientAgentImpl

Specified by:

createClientAgent in interface JVMProcessRemote

Parameters:

agentName - agent name

Returns:

client agent remote interface

Throws:

java.lang.Exception

shutdownClientAgent

public void shutdownClientAgent(ClientAgentRemote clientAgent)

Shuts down the given client agent. Currently not used because agent's shutdown method is called directly.

Specified by:

shutdownClientAgent in interface JVMProcessRemote

Parameters:

clientAgent - ClientAgentRemote

shutdown

public void shutdown()

Terminates the JVM by calling System.exit.

Specified by:

shutdown in interface JVMProcessRemote

ping

public void ping()

Renews a lease on the agent. Used to keep warmedUp JVM running

getInstance

public static JVMProcess getInstance()

Returns the instance representing this JVM

Returns:

JVMProcess

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

JVM Process entry point.

Throws:

java.lang.Exception

unreferenced

public void unreferenced()

Called by RMI runtime if the factory got shutdown

Specified by:

unreferenced in interface java.rmi.server.Unreferenced
