Method Detail

execute

public void execute(java.lang.Runnable task)

Description copied from interface: BlockingExecutor

Executes the given command at some time in the future. The command may execute in a new thread, in a pooled thread, or in the calling thread, at the discretion of the Executor implementation. The call may block or not block, depending on the configuration of the executor.

Specified by:

execute in interface java.util.concurrent.Executor

Specified by:

execute in interface BlockingExecutor

Overrides:

execute in class java.util.concurrent.ThreadPoolExecutor

Parameters:

task - the task to submit

executeBlocking

public void executeBlocking(java.lang.Runnable task)
                     throws java.util.concurrent.RejectedExecutionException,
                            java.lang.InterruptedException

Description copied from interface: BlockingExecutor

Execute a task, blocking until it can be accepted, or until the calling thread is interrupted.

Specified by:

executeBlocking in interface BlockingExecutor

Parameters:

task - the task to submit

Throws:

StoppedExecutorException - if the executor was shut down before the task was accepted

ThreadCreationException - if a thread could not be created for some reason

java.util.concurrent.RejectedExecutionException - if execution is rejected for some other reason

java.lang.InterruptedException - if the current thread was interrupted before the task could be accepted

executeBlocking

public void executeBlocking(java.lang.Runnable task,
                            long timeout,
                            java.util.concurrent.TimeUnit unit)
                     throws java.util.concurrent.RejectedExecutionException,
                            java.lang.InterruptedException

Description copied from interface: BlockingExecutor

Execute a task, blocking until it can be accepted, a timeout elapses, or the calling thread is interrupted.

Specified by:

executeBlocking in interface BlockingExecutor

Parameters:

task - the task to submit

timeout - the amount of time to wait

unit - the unit of time

Throws:

ExecutionTimedOutException - if the timeout elapsed before a task could be accepted

StoppedExecutorException - if the executor was shut down before the task was accepted

ThreadCreationException - if a thread could not be created for some reason

java.util.concurrent.RejectedExecutionException - if execution is rejected for some other reason

java.lang.InterruptedException - if the current thread was interrupted before the task could be accepted

executeNonBlocking

public void executeNonBlocking(java.lang.Runnable task)
                        throws java.util.concurrent.RejectedExecutionException

Description copied from interface: BlockingExecutor

Execute a task, without blocking.

Specified by:
