Class GCspy

java.lang.Object

org.mmtk.utility.gcspy.GCspy

public class GCspy
extends Object

This class implements collector-independent GCspy functionality to start the GCspy server. It handles command-line parameters for port number, whether the VM should wait for a GCspy client to connect, and tile size. Most importantly, it calls the Plan's startGCspyServer method which creates a new ServerInterpreter, and adds events and space drivers.
