Class Continuation.ExternalContinuation<R,E extends Exception>

java.lang.Object
  rice.Continuation.ExternalContinuation<R,E>

All Implemented Interfaces:

Continuation<R,E>

Enclosing interface:

Continuation<R,E extends Exception>

public static class Continuation.ExternalContinuation<R,E extends Exception>
extends Object
implements Continuation<R,E>

This class provides a continuation which is designed to be used from an external thread. Applications should construct this continuation pass it in to the appropriate method, and then call sleep(). Once the thread is woken up, the user should check exceptionThrown() to determine if an error was caused, and then call getException() or getResult() as appropriate.
