Class GassServerContainer

java.lang.Object
  org.gridbus.broker.farming.globus.GassServerContainer

public final class GassServerContainer
extends java.lang.Object

This class has utility methods for working with GASS Servers. It implements the Singleton pattern, since we need only one GassServer on the broker side to handle file movement requests etc.
