Executor, ExecutorService

public class CachedThreadPoolExecutor
extends ThreadPoolExecutor

CachedThreadPoolExecutor

public CachedThreadPoolExecutor(int maximumPoolSize,
                                int maximumQueueSize,
                                String threadPrefix,
                                Class<?> loggerIdentity)

Constructs an instance.

Parameters:

maximumQueueSize - the capacity of the queue.

threadPrefix - the name prefix for threads created by this executor.

loggerIdentity - the class to use as logger name for logging uncaught exceptions from the threads.
