Class MethodCall

java.lang.Object
  org.jgroups.blocks.MethodCall
      org.jboss.cache.marshall.MethodCall

All Implemented Interfaces:

Externalizable, Serializable

public class MethodCall
extends org.jgroups.blocks.MethodCall

An extension of the JGroups MethodCall class. The reason for this subclass is a minor optimisation in the way method IDs are dealt with. The JGroups class of the same name uses a short as a method id, which is more efficient as far as network streaming is concerned.

However, JBossCache uses this id for a lot of == and switch comparisons. Java, being an integer oriented virtual machine, goes through a lot of extra steps when performing such simple comparisons or arithmetic on non-integer numeric types.
