Method Detail

queueTimedJob

void queueTimedJob(java.lang.Runnable job,
                   long offset)

Run a job after a given delay.

Parameters:

job - The Runnable to execute.

offset - The delay in milliseconds.

queueTimedJob

void queueTimedJob(java.lang.Runnable job,
                   java.lang.String name,
                   long offset,
                   boolean runOnTickerAnyway,
                   boolean noDupes)

Run a job after a given delay.

Parameters:

job - The Runnable to execute.

name - The name of the thread to run it.

offset - The delay in milliseconds.

runOnTickerAnyway - If true, start the job from the Ticker thread even if we could pass it directly through to the Executor. This is needed for increasing thread priorities, since the Ticker runs at a high priority, and for some tests.

noDupes - If true, ignore the job if it is already queued. Implies runOnTickerAnyway. WARNING: This does not guarantee that we don't run multiple copies of the job simultaneously! You must ensure adequate locking. Worse, if the job takes an unexpectedly long time, you could end up with many copies of the job running simultaneously.

getExecutor

Executor getExecutor()

Get the underlying Executor.

removeQueuedJob

void removeQueuedJob(java.lang.Runnable job)

Remove a queued job.

queueTimedJobAbsolute

void queueTimedJobAbsolute(java.lang.Runnable runner,
                           java.lang.String name,
                           long time,
                           boolean runOnTickerAnyway,
                           boolean noDupes)

Run a job at a specified absolute time.

Parameters:

job - The Runnable to execute.

name - The name of the thread to run it.

time - The time at which to run the job.

runOnTickerAnyway - If true, start the job from the Ticker thread even if we could pass it directly through to the Executor. This is needed for increasing thread priorities, since the Ticker runs at a high priority, and for some tests.

noDupes - If true, ignore the job if it is already queued. Implies runOnTickerAnyway. WARNING: This does not guarantee that we don't run multiple copies of the job simultaneously! You must ensure adequate locking. Worse, if the job takes an unexpectedly long time, you could end up with many copies of the job running simultaneously.
