Class FutureCallbackFailureHandler

java.lang.Object

org.threadly.concurrent.future.AbstractFutureCallbackFailureHandler

org.threadly.concurrent.future.FutureCallbackFailureHandler

All Implemented Interfaces:

FutureCallback<java.lang.Object>

public class FutureCallbackFailureHandler
extends AbstractFutureCallbackFailureHandler

An implementation of FutureCallback where the result is ignored and failures are delegated to a lambda provided at construction. This can allow you to easily do an action only on a failure condition.

See AbstractFutureCallbackFailureHandler for a similar implementation except using an abstract class rather than accepting a lambda.
