Method Summary

Modifier and Type	Method	Description
ExecutorService	newExecutor(int threads, int queueSize, String daemonName, String executorName)	Construct a new ExecutorService with a specified queue size for the backlog of tasks.
ExecutorService	newExecutor(int threads, String daemonName, String executorName)	Construct a new ExecutorService with an unbounded queue size ({@link Integer#MAX_VALUE). For CPU-intensive tasks, it is a good idea to use the value of {@link Runtime#availableProcessors()} (or a reasonable multiple of it based on the tasks) for the threads parameter to ensure that the CPU is fully utilized.
ExecutorService	newExecutor(String daemonName, String executorName)	Construct a new ExecutorService with an unbounded queue size and a thread pool size equal to the value of Runtime.availableProcessors() so that one thread per core is started.

newExecutor

public ExecutorService newExecutor(String daemonName,
                                   String executorName)

Description copied from interface: ExecutorFactory

Construct a new ExecutorService with an unbounded queue size and a thread pool size equal to the value of Runtime.availableProcessors() so that one thread per core is started.

Specified by:

newExecutor in interface ExecutorFactory

Returns:

newExecutor

public ExecutorService newExecutor(int threads,
                                   String daemonName,
                                   String executorName)

Construct a new ExecutorService with an unbounded queue size ({@link Integer#MAX_VALUE). For CPU-intensive tasks, it is a good idea to use the value of {@link Runtime#availableProcessors()} (or a reasonable multiple of it based on the tasks) for the threads parameter to ensure that the CPU is fully utilized.

Returns:

An ExecutorService pool

newExecutor

public ExecutorService newExecutor(int threads,
                                   int queueSize,
                                   String daemonName,
                                   String executorName)

Description copied from interface: ExecutorFactory

Construct a new ExecutorService with a specified queue size for the backlog of tasks. When the queue is full, the pool may block, discard the incoming task, or throw an exception. This behavior is dependent on the implementation of the ExecutorService. For CPU-intensive tasks, it is a good idea to use the value of Runtime.availableProcessors() (or a reasonable multiple of it based on the tasks) for the threads parameter to ensure that the CPU is fully utilized.

Returns:

An ExecutorService pool
