Class ContextualExecutorService

java.lang.Object

org.jboss.resteasy.concurrent.ContextualExecutorService

All Implemented Interfaces:

Executor, ExecutorService

Direct Known Subclasses:

ContextualScheduledExecutorService

public class ContextualExecutorService
extends Object
implements ExecutorService

An executor which wraps runnables and callables to capture the context of the current thread.

If a server is managed it's the responsibility of the user or container to manage the lifecycle of the wrapped executor service.

Note: if the executor is consider managed, for example running in a Jakarta EE environment, the following methods are effectively ignored.

• shutdown()
• shutdownNow()
• isShutdown()
• isTerminated()
• awaitTermination(long, TimeUnit)

Since:

5.0.0
