com.aspc.DBObj.GlobalKey

public final class GlobalKey
extends java.lang.Object

GlobalKey is a combination of a two GlobalId's one for the value of the record key and the other for the GlobalId for the class of the DBObject. OPTIMIZE: taking the synchronization lock is the expensive bit so when calling a synchronized method multiple times it may be cheaper to synchronize the object we wait to call the method of first.
