Class CompletableContext<T>

  • Type Parameters:
    T - the result type
    public class CompletableContext<T>
extends java.lang.Object
    A thread-safe completable context that allows listeners to be attached. This class relies on the CompletableFuture for the concurrency logic. However, it does not accept Throwable as an exceptional result. This allows attaching listeners that only handle Exception.
