Method Detail

hasTaskAsync

RFuture<Boolean> hasTaskAsync(String taskId)

Returns true if this Executor Service has task by taskId awaiting for execution and/or currently in execution

Parameters:

taskId - - id of task

Returns:

true if this Executor Service has task

getTaskCountAsync

RFuture<Integer> getTaskCountAsync()

Returns amount of tasks awaiting for execution and/or currently in execution.

Returns:

amount of tasks

getTaskIdsAsync

RFuture<Set<String>> getTaskIdsAsync()

Returns list of task ids awaiting for execution and/or currently in execution.

Returns:

task ids

cancelTaskAsync

RFuture<Boolean> cancelTaskAsync(String taskId)

Cancel task by id

Parameters:

taskId - - id of task

Returns:

true if task has been canceled successfully

RExecutorFuture.getTaskId()

deleteAsync

RFuture<Boolean> deleteAsync()

Deletes executor request queue and state objects

Returns:

true if any of objects were deleted

submitAsync

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

Submits task for execution asynchronously

Type Parameters:

T - type of return value

Parameters:

task - - task to execute

Returns:

Future object

submitAsync

<T> RExecutorFuture<T> submitAsync(Callable<T> task,
                                   long timeToLive,
                                   TimeUnit timeUnit)

Submits a value-returning task with defined timeToLive parameter for execution asynchronously. Returns a Future representing the pending results of the task. The Future's get method will return the task's result upon successful completion.

Type Parameters:

T - the type of the task's result

Parameters:

task - the task to submit

timeToLive - - time to live interval

timeUnit - - unit of time to live interval

Returns:

a Future representing pending completion of the task

submitAsync

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

Submits tasks batch for execution asynchronously. 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

submitAsync

RExecutorFuture<?> submitAsync(Runnable task)

Submits task for execution asynchronously

Parameters:

task - - task to execute

Returns:

Future object

submitAsync

RExecutorFuture<?> submitAsync(Runnable task,
                               long timeToLive,
                               TimeUnit timeUnit)

Submits a task with defined timeToLive parameter for execution asynchronously. Returns a Future representing task completion. The Future's get method will return the task's result upon successful completion.

Parameters:

task - the task to submit

timeToLive - - time to live interval

timeUnit - - unit of time to live interval

Returns:

a Future representing pending completion of the task

submitAsync

RExecutorBatchFuture submitAsync(Runnable... tasks)

Submits tasks batch for execution asynchronously. 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
