Method Detail

getTimerExecutor

public ScheduledExecutorService getTimerExecutor()

Returns a singleton instance of ScheduledExecutorService.

Specified by:

getTimerExecutor in interface org.jboss.weld.manager.api.ExecutorServices

Returns:

A managed instance of ScheduledExecutorService

invokeAllAndCheckForExceptions

public <T> List<Future<T>> invokeAllAndCheckForExceptions(Collection<? extends Callable<T>> tasks)

Specified by:

invokeAllAndCheckForExceptions in interface org.jboss.weld.manager.api.ExecutorServices

invokeAllAndCheckForExceptions

public <T> List<Future<T>> invokeAllAndCheckForExceptions(org.jboss.weld.manager.api.ExecutorServices.TaskFactory<T> factory)

Specified by:

invokeAllAndCheckForExceptions in interface org.jboss.weld.manager.api.ExecutorServices

checkForExceptions

protected <T> List<Future<T>> checkForExceptions(List<Future<T>> futures)

getThreadPoolSize

protected abstract int getThreadPoolSize()

Indicates the maximum number of threads in this thread pool. If the value is unknown or if the max number of threads is not bounded this method should return -1

cleanup

public void cleanup()

Specified by:

cleanup in interface org.jboss.weld.bootstrap.api.Service

shutdown

protected void shutdown()

wrap

public <T> Collection<? extends Callable<T>> wrap(Collection<? extends Callable<T>> tasks)

This method is invoked with the body of invokeAllAndCheckForExceptions(java.util.Collection) It allows to wrap the tasks with some additional logic. For instance, Weld's CommonForkJoinPoolExecutorServices overrides this in order to set TCCL to null prior to execution.
