Method Detail

getThreadProvider

ThreadProvider getThreadProvider()

Returns:

The underlying thread provider.

newFixedThreadPool

ThreadPoolExecutor newFixedThreadPool(int threads,
                                      String threadNamePrefix)

Creates a new fixed size ThreadPoolExecutor.

It's using a blocking queue of maximum 1000 elements and the rejection policy is set to block until the queue can accept the task. These settings are required to cap the queue, to make sure the timeouts are reasonable for most jobs.

Parameters:

threads - the number of threads

threadNamePrefix - a label to identify the threads; useful for profiling.

Returns:

the new ExecutorService

newFixedThreadPool

ThreadPoolExecutor newFixedThreadPool(int threads,
                                      String threadNamePrefix,
                                      int queueSize)

Creates a new fixed size ThreadPoolExecutor.

It's using a blocking queue of maximum queueSize elements and the rejection policy is set to block until the queue can accept the task. These settings are required to cap the queue, to make sure the timeouts are reasonable for most jobs.

Parameters:

threads - the number of threads

threadNamePrefix - a label to identify the threads; useful for profiling.

queueSize - the size of the queue to store Runnables when all threads are busy

Returns:

the new ExecutorService

newScheduledThreadPool

ScheduledExecutorService newScheduledThreadPool(String threadNamePrefix)

Creates an executor for recurring tasks

Parameters:

threadNamePrefix - a label to identify the threads; useful for profiling.

Returns:

instance of ScheduledExecutorService
