ScheduledExecutorServiceWrapper

public ScheduledExecutorServiceWrapper(java.util.concurrent.ScheduledExecutorService scheduler)

Constructs a new wrapper with the provided scheduler implementation.

Parameters:

scheduler - ScheduledExecutorService implementation

Method Detail

scheduleWithFixedDelay

public void scheduleWithFixedDelay(java.lang.Runnable task,
                                   long initialDelay,
                                   long recurringDelay)

Description copied from interface: SubmitterScheduler

Schedule a fixed delay recurring task to run. The recurring delay time will be from the point where execution has finished. So the execution frequency is the recurringDelay + runtime for the provided task.

Unlike ScheduledExecutorService if the task throws an exception, subsequent executions are NOT suppressed or prevented. So if the task throws an exception on every run, the task will continue to be executed at the provided recurring delay (possibly throwing an exception on each execution).

Parameters:

task - runnable to be executed

initialDelay - delay in milliseconds until first run

recurringDelay - delay in milliseconds for running task after last finish

scheduleAtFixedRate

public void scheduleAtFixedRate(java.lang.Runnable task,
                                long initialDelay,
                                long period)

Description copied from interface: SubmitterScheduler

Schedule a fixed rate recurring task to run. The recurring delay will be the same, regardless of how long task execution takes. A given runnable will not run concurrently (unless it is submitted to the scheduler multiple times). Instead of execution takes longer than the period, the next run will occur immediately (given thread availability in the pool).

Unlike ScheduledExecutorService if the task throws an exception, subsequent executions are NOT suppressed or prevented. So if the task throws an exception on every run, the task will continue to be executed at the provided recurring delay (possibly throwing an exception on each execution).

Parameters:

task - runnable to be executed

initialDelay - delay in milliseconds until first run

period - amount of time in milliseconds between the start of recurring executions
