Interface Continuation

All Known Implementing Classes:

Continuation.ExternalContinuation, Continuation.ListenerContinuation, Continuation.StandardContinuation, ContinuationMessage, DistPASTRegrTest.TestCommand, PastRegrTest.TestCommand, PastRegrTest.TestExceptionCommand

public interface Continuation

Asynchronously receives the result to a given method call, using the command pattern. Implementations of this class contain the remainder of a computation which included an asynchronous method call. When the result to the call becomes available, the receiveResult method on this command is called.

Nested Class Summary

static class	Continuation.ExternalContinuation This class provides a continuation which is designed to be used from an external thread.
static class	Continuation.ListenerContinuation This class is a Continuation provided for simplicity which listens for any errors and ignores any success values.
static class	Continuation.StandardContinuation This class is a Continuation provided for simplicity which passes any errors up to the parent Continuation which it is constructed with.

Method Summary

void	receiveException(java.lang.Exception result) Called when an execption occured as a result of the previous command.
void	receiveResult(java.lang.Object result) Called when a previously requested result is now availble.
