All Implemented Interfaces:

Runnable, ClassServerDelegate, ClientConnectionHandler, ClientConnectionStatusHandler

public class ClassServerDelegateImpl
extends AbstractClassServerDelegate

Wrapper around an incoming socket connection, whose role is to receive the names of classes to load from the classpath, then send the class files' contents (or bytecode) to the remote client.

Instances of this class are part of the JPPF dynamic class loading mechanism. They enable remote nodes to dynamically load classes from the JVM that run's the class server.
