java.util.concurrent.AbstractExecutorService

org.glassfish.grizzly.threadpool.AbstractThreadPool

org.glassfish.grizzly.threadpool.SyncThreadPool

All Implemented Interfaces:

Thread.UncaughtExceptionHandler, Executor, ExecutorService, MonitoringAware<ThreadPoolProbe>

public class SyncThreadPool
extends AbstractThreadPool

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