build()
Build the configured executor
|
ExecutorBuilder<E> |
withDefaultThreadGroup()
Use the system default thread group for the threads we create.
|
ThreadPoolExecutorBuilder<E> |
withKeepAlive()
Core threads for the executor built by this factory will never timeout (default for single threaded builders).
|
ThreadPoolExecutorBuilder<E> |
withKeepAlive(long keepAlive,
java.util.concurrent.TimeUnit keepAliveUnits)
Threads for the executor built by this factory will timeout (terminate) after the specified period.
|
ThreadPoolExecutorBuilder<E> |
withQueueLimit(int queueLimit)
The executor built by this factory will limit the number of queued tasks; default is unlimited.
|
ThreadPoolExecutorBuilder<E> |
withRejectedExecutionHandler(java.util.concurrent.RejectedExecutionHandler rejectedExecutionHandler)
Set the
RejectedExecutionHandler for the executor built by this factory. |
ExecutorBuilder<E> |
withThreadGroup(java.lang.ThreadGroup threadGroup)
Threads for the executor built by this factory will all be (transitively) members of
threadGroup,
but may directly reside in a child thread group. |
ThreadPoolExecutorBuilder<E> |
withThreadPriority(int threadPriority)
Specify the priority of threads that service the executor built by this factory (default to
Thread.NORM_PRIORITY) |
ThreadPoolExecutorBuilder<E> |
withUncaughtExceptionHandler(java.lang.Thread.UncaughtExceptionHandler uncaughtExceptionHandler)
Set the
Thread.UncaughtExceptionHandler for threads that service executors built by this factory. |
