Class LookupTable

java.lang.Object

host.anzo.simon.LookupTable

All Implemented Interfaces:

LookupTableMBean

public class LookupTable
extends Object
implements LookupTableMBean

This class is "the brain" of SIMON. It saves all known remote object - name relations, as well as hashcodes for all the methods in the remote object. If a object is getting unreferenced over the network connection, it gets "informed" by the unreferenced() method, if SimonUnreferenced is implemented.
