Class PrioritySchedulerServiceWrapper

java.lang.Object

org.threadly.concurrent.wrapper.compatibility.PrioritySchedulerServiceWrapper

All Implemented Interfaces:

java.util.concurrent.Executor, java.util.concurrent.ExecutorService, java.util.concurrent.ScheduledExecutorService

public class PrioritySchedulerServiceWrapper
extends java.lang.Object

This is a wrapper for PriorityScheduler to be a drop in replacement for any ScheduledExecutorService (AKA the ScheduledThreadPoolExecutor interface). It does make some performance sacrifices to adhere to this interface, but those are pretty minimal. The largest compromise in here is easily scheduleAtFixedRate (which you should read the javadocs for if you need).

Since:

4.6.0 (since 1.0.0 as org.threadly.concurrent.PriorityScheduledExecutorServiceWrapper)

Constructor Detail

PrioritySchedulerServiceWrapper

public PrioritySchedulerServiceWrapper(PriorityScheduler scheduler)

Constructs a new wrapper to adhere to the ScheduledExecutorService interface.

Parameters:

scheduler - PriorityScheduler implementation to rely on

PrioritySchedulerServiceWrapper

public PrioritySchedulerServiceWrapper(PriorityScheduler scheduler,
                                       TaskPriority taskPriority)

Constructs a new wrapper to adhere to the ScheduledExecutorService interface.

Parameters:

scheduler - PriorityScheduler implementation to rely on

taskPriority - Priority for all tasks submitted to the parent scheduler

Method Detail

shutdown

public void shutdown()

shutdownNow

public java.util.List<java.lang.Runnable> shutdownNow()

This call will stop the processor as quick as possible. Any tasks which are awaiting execution will be canceled and returned as a result to this call.

Unlike ExecutorService implementation there is no attempt to stop any currently execution tasks.

This method does not wait for actively executing tasks toterminate. Use awaitTermination to do that.

Returns:

list of tasks that never commenced execution

isTerminated

public boolean isTerminated()

awaitTermination

public boolean awaitTermination(long timeout,
                                java.util.concurrent.TimeUnit unit)
                         throws java.lang.InterruptedException

Throws:
