Method Detail

submit

<T> RExecutorFuture<T> submit(Callable<T> task)

Submits a value-returning task for execution synchronously and returns a Future representing the pending results of the task. The Future's get method will return the task's result upon successful completion.

Specified by:

submit in interface ExecutorService

Type Parameters:

T - the type of the task's result

Parameters:

task - the task to submit

Returns:

a Future representing pending completion of the task

submit

RExecutorBatchFuture submit(Callable<?>... tasks)

Submits tasks batch for execution synchronously. All tasks are stored to executor request queue atomically, if case of any error none of tasks will be added.

Parameters:

tasks - - tasks to execute

Returns:

Future object

submit

<T> RExecutorFuture<T> submit(Runnable task,
                              T result)

Submits a Runnable task for execution and returns a Future representing that task. The Future's get method will return the given result upon successful completion.

Specified by:

submit in interface ExecutorService

Type Parameters:

T - the type of the result

Parameters:

task - the task to submit

result - the result to return

Returns:

a Future representing pending completion of the task

submit

RExecutorFuture<?> submit(Runnable task)

Submits a Runnable task for execution and returns a Future representing that task. The Future's get method will return null upon successful completion.

Specified by:

submit in interface ExecutorService

Parameters:

task - the task to submit

Returns:

a Future representing pending completion of the task

submit

RExecutorBatchFuture submit(Runnable... tasks)

Submits tasks batch for execution synchronously. All tasks are stored to executor request queue atomically, if case of any error none of tasks will be added.

Parameters:

tasks - - tasks to execute

Returns:

Future object

getName

String getName()

Returns executor name

Returns:

name of service

delete

boolean delete()

Deletes executor request queue and state objects

Returns:

true if any of objects were deleted

registerWorkers

void registerWorkers(int workers)

Register workers

Parameters:

workers - - workers amount

registerWorkers

void registerWorkers(int workers,
                     ExecutorService executor)

Register workers with custom executor

Parameters:

workers - - workers amount

executor - - executor instance

countActiveWorkers

int countActiveWorkers()

Returns active worker groups

Returns:

active worker groups count

cancelTask

boolean cancelTask(String taskId)

Cancels task by id

Parameters:

taskId - - id of task

Returns:

true if task has been canceled successfully

RExecutorFuture.getTaskId()

execute

void execute(Runnable... tasks)

Submits tasks batch for execution synchronously. All tasks are stored to executor request queue atomically, if case of any error none of tasks will be added.

Parameters:

tasks - - tasks to execute
