Class GCspy

java.lang.Object
  org.mmtk.utility.gcspy.GCspy

public class GCspy
extends Object
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.

Field Summary

Method Summary

Initialization

postBoot

public static void postBoot()

The boot method is called by the runtime immediately after command-line arguments are available. Note that allocation must be supported prior to this point because the runtime infrastructure may require allocation in order to parse the command line arguments.

getGCspyPort

public static int getGCspyPort()

Get the number of the port that GCspy communicates on

Returns:: the GCspy port number

getGCspyWait

public static boolean getGCspyWait()

Should the VM wait for GCspy to connect?

Returns:: whether the VM should wait for the visualiser to connect

startGCspyServer

public static void startGCspyServer()

Start the GCspy server. WARNING: allocates memory indirectly
