public LooperDelegatingScheduler(Looper looper)

Method Detail

getIdleState

public Scheduler.IdleState getIdleState()

Description copied from class: Scheduler

Retrieves the current idling state of this Scheduler.

Overrides:

getIdleState in class Scheduler

Returns:

The current idle state of this Scheduler.

See Also:

Scheduler.setIdleState(IdleState), Scheduler.isPaused()

setIdleState

public void setIdleState(Scheduler.IdleState idleState)

Description copied from class: Scheduler

Sets the current idling state of this Scheduler. If transitioning to the Scheduler.IdleState.UNPAUSED state any tasks scheduled to be run at or before the current time will be run, and if transitioning to the Scheduler.IdleState.CONSTANT_IDLE state all scheduled tasks will be run and the clock advanced to the time of the last runnable.

Overrides:

setIdleState in class Scheduler

Parameters:

idleState - The new idle state of this Scheduler.

See Also:

Scheduler.setIdleState(IdleState), Scheduler.isPaused()

getCurrentTime

public long getCurrentTime()

Description copied from class: Scheduler

Get the current time (as seen by the scheduler), in milliseconds.

Overrides:

getCurrentTime in class Scheduler

Returns:

Current time in milliseconds.

pause

public void pause()

Description copied from class: Scheduler

Pause the scheduler. Equivalent to setIdleState(PAUSED).

Overrides:

pause in class Scheduler

See Also:

Scheduler.unPause(), Scheduler.setIdleState(IdleState)

unPause

public void unPause()

Description copied from class: Scheduler

Un-pause the scheduler. Equivalent to setIdleState(UNPAUSED).

Overrides:

unPause in class Scheduler

See Also:

Scheduler.pause(), Scheduler.setIdleState(IdleState)

isPaused

public boolean isPaused()

Description copied from class: Scheduler

Determine if the scheduler is paused.

Overrides:

isPaused in class Scheduler

Returns:

true if it is paused.

post

public void post(Runnable runnable)

Description copied from class: Scheduler

Add a runnable to the queue.

Overrides:

post in class Scheduler

Parameters:

runnable - Runnable to add.

postDelayed

public void postDelayed(Runnable runnable,
                        long delayMillis)

Description copied from class: Scheduler

Add a runnable to the queue to be run after a delay.

Overrides:

postDelayed in class Scheduler

Parameters:

runnable - Runnable to add.

delayMillis - Delay in millis.

postDelayed

public void postDelayed(Runnable runnable,
                        long delay,
                        TimeUnit unit)

Description copied from class: Scheduler

Add a runnable to the queue to be run after a delay.

Overrides:

postDelayed in class Scheduler

postAtFrontOfQueue

public void postAtFrontOfQueue(Runnable runnable)

Description copied from class: Scheduler

Add a runnable to the head of the queue.

Overrides:

postAtFrontOfQueue in class Scheduler

Parameters:

runnable - Runnable to add.

remove

public void remove(Runnable runnable)

Description copied from class: Scheduler

Remove a runnable from the queue.

Overrides:

remove in class Scheduler

Parameters:

runnable - Runnable to remove.

advanceToLastPostedRunnable

public boolean advanceToLastPostedRunnable()

Description copied from class: Scheduler

Run all runnables in the queue, and any additional runnables they schedule that are scheduled before the latest scheduled runnable currently in the queue.

Overrides:

advanceToLastPostedRunnable in class Scheduler

Returns:

True if a runnable was executed.

advanceToNextPostedRunnable

public boolean advanceToNextPostedRunnable()

Description copied from class: Scheduler

Run the next runnable in the queue.

Overrides:

advanceToNextPostedRunnable in class Scheduler

Returns:

True if a runnable was executed.

public boolean advanceBy(long interval)

Description copied from class: Scheduler

Run all runnables that are scheduled to run in the next time interval.

Overrides:

advanceBy in class Scheduler

Parameters:

interval - Time interval (in millis).
