  java.util.concurrent.AbstractExecutorService
      org.glassfish.grizzly.threadpool.AbstractThreadPool
          org.glassfish.grizzly.threadpool.SyncThreadPool

All Implemented Interfaces:

public class SyncThreadPool
extends AbstractThreadPool

ExecutorService implementation, which function the similar way as former Grizzly 1.x Pipeline based thread pools. The SyncThreadPool is sychronized similar way as Grizzly 1.x Pipeline, which makes thread pool more accurate when deciding to create or not additional worker threads.

Description copied from class: AbstractThreadPool

must hold statelock while calling this method.

Overrides:

startWorker in class AbstractThreadPool

onWorkerStarted

protected void onWorkerStarted(AbstractThreadPool.Worker worker)

Description copied from class: AbstractThreadPool

Method is called by AbstractThreadPool.Worker, when it's starting AbstractThreadPool.Worker.run() method execution, which means, that ThreadPool's thread is getting active and ready to process tasks. This method is called from AbstractThreadPool.Worker's thread.

Overrides:

Description copied from class: AbstractThreadPool

Method is called by AbstractThreadPool.Worker, when it's completing AbstractThreadPool.Worker.run() method execution, which in most cases means, that ThreadPool's thread will be released. This method is called from AbstractThreadPool.Worker's thread.

Overrides:

onWorkerExit in class AbstractThreadPool
