Package org.jboss.marshalling

Class ModularClassTable

java.lang.Object

org.jboss.marshalling.ModularClassTable

All Implemented Interfaces:

ClassTable

public final class ModularClassTable
extends java.lang.Object
implements ClassTable

A class table which implements an alternate class resolution strategy based on JBoss Modules. Each class name is stored along with its corresponding module identifier, which allows the object graph to be exactly reconstituted on the remote side. This class should only be used when the marshalling and unmarshalling side share the same class files.
