Method Summary

Modifier and Type	Method and Description
void	awaitPausing() Pauses the task, which lets the thread finish without completing the task.
boolean	cancel(boolean cancelIfRunnning)
long	getLong() A Type Specific get method that allows to reduce (un)boxing of primtives.
long	getLong(long timeout, java.util.concurrent.TimeUnit unit) Waits if necessary for at most the given time for the computation to complete, and then retrieves its result, if available.
boolean	isCancelled()
boolean	isDone()
boolean	isPaused() Helper function to detect if the task is currently paused.
boolean	isSuccessful() Quality of life function that allows to detect if no cancellation/exception was applied to this task and it completed on its own.
void	pause() Pauses the task, which lets the thread finish without completing the task.
void	resume() Continues the task if it wasn't already completed.
void	run()

Method Detail

run

public void run()

Specified by:

run in interface java.lang.Runnable

Specified by:

run in interface java.util.concurrent.RunnableFuture<java.lang.Long>

cancel

public boolean cancel(boolean cancelIfRunnning)

Specified by:

cancel in interface java.util.concurrent.Future<java.lang.Long>

getLong

public long getLong()
             throws java.lang.InterruptedException,
                    java.util.concurrent.ExecutionException

Description copied from interface: LongTask

A Type Specific get method that allows to reduce (un)boxing of primtives. Waits if necessary for the computation to complete, and then retrieves its result.

Specified by:

getLong in interface LongTask

Returns:

the computed result as primitive

Throws:

java.lang.InterruptedException - if the current thread was interrupted while waiting

java.util.concurrent.ExecutionException - if the computation threw an exception

getLong

public long getLong(long timeout,
                    java.util.concurrent.TimeUnit unit)
             throws java.lang.InterruptedException,
                    java.util.concurrent.ExecutionException,
                    java.util.concurrent.TimeoutException

Description copied from interface: LongTask

Waits if necessary for at most the given time for the computation to complete, and then retrieves its result, if available.

Specified by:

getLong in interface LongTask

Parameters:

timeout - the maximum time to wait

unit - the time unit of the timeout argument

Returns:

the computed result as primitive

Throws:

java.lang.InterruptedException - if the current thread was interrupted while waiting

java.util.concurrent.ExecutionException - if the computation threw an exception

java.util.concurrent.TimeoutException - if the wait timed out

isCancelled

public boolean isCancelled()

Specified by:

isCancelled in interface java.util.concurrent.Future<java.lang.Long>

isDone

public boolean isDone()

Specified by:

isDone in interface java.util.concurrent.Future<java.lang.Long>

isPaused

public boolean isPaused()

Description copied from interface: LongTask

Helper function to detect if the task is currently paused.

Specified by:

isPaused in interface LongTask

Returns:

true if paused

isSuccessful

public boolean isSuccessful()

Description copied from interface: LongTask

Quality of life function that allows to detect if no cancellation/exception was applied to this task and it completed on its own.

Specified by:

isSuccessful in interface LongTask

Returns:

true if it was properly completed

pause

public void pause()

Description copied from interface: LongTask

Pauses the task, which lets the thread finish without completing the task. Tasks are written in the way where they can pause without any issues. This won't be instant, as this function is applied asynchronous and doesn't check if the thread paused. So make sure it had the time to pause.

Specified by:

pause in interface LongTask

awaitPausing

public void awaitPausing()

Description copied from interface: LongTask

Pauses the task, which lets the thread finish without completing the task. Tasks are written in the way where they can pause without any issues. This won't be instant, as this function is applied asynchronous. It will await the pausing of the task.

Specified by:

awaitPausing in interface LongTask

resume

public void resume()

Description copied from interface: LongTask

Continues the task if it wasn't already completed. This is done by resubmitting the task to the executor provided.

Specified by:

resume in interface LongTask
