Enclosing interface:

Continuation

public static class Continuation.ExternalContinuation

extends java.lang.Object

implements Continuation

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 apprpritate.
