All Implemented Interfaces:

Direct Known Subclasses:
Continuation.ExternalRunnable
Enclosing interface:
Continuation

public abstract static class Continuation.ExternalContinuationRunnable
extends java.lang.Object
implements java.lang.Runnable

This class is used when you want to run some task on the selector thread and wait for it to return its result in a Continuation. It is essentially a covnenience object which combines the functionality of a Runnable that can be invoked on the Selector with an ExternalContinuation that it will wait on. Override the run(Continuation) method then call invoke() to get the result or Exception from the operation. The current thread will block on invoke until the continuation returns a result or an exception.
