Class SameThreadSubmitterExecutor

java.lang.Object

org.threadly.concurrent.SameThreadSubmitterExecutor

All Implemented Interfaces:

java.util.concurrent.Executor, SubmitterExecutor

public class SameThreadSubmitterExecutor
extends java.lang.Object
implements SubmitterExecutor

A SubmitterExecutor that will run all provided tasks immediately in the same thread that is invoking into it with the task. This is different from calling the runnable directly only in that no exceptions will propagate out. In the case of just execute(Runnable) thrown exceptions will be provided to ExceptionUtils.handleException(Throwable) to be handled. Otherwise thrown exceptions will be represented within their returned ListenableFuture.

Since:

1.2.0
