Class AbstractFutureCallbackResultHandler<T>

java.lang.Object

org.threadly.concurrent.future.AbstractFutureCallbackResultHandler<T>

Type Parameters:

T - Type of result returned

All Implemented Interfaces:

FutureCallback<T>

Direct Known Subclasses:

FutureCallbackResultHandler

public abstract class AbstractFutureCallbackResultHandler<T>
extends java.lang.Object
implements FutureCallback<T>

An abstract implementation of FutureCallback where failures are ignored. This can allow you to easily do an action only when a result is produced condition (with the result provided by FutureCallback.handleResult(Object).

It is important to know that if a failure did occur, and your using this, unless your using some other means to detect it (like ListenableFuture#addListener(Runnable), you may never know the computation is complete.

For a simpler construction using a lambda look at FutureCallbackResultHandler.
