Method Detail

executeLater

public final void executeLater(Runnable task)

Adds a task that will be run when drain() is called.

This is useful for cases where you want to enqueue a task while under a lock of your own, but don't want the tasks to be run under your lock (for fear of deadlock). You can call this method in the lock, and call drain() outside the lock.

execute

public final void execute(Runnable task)

Specified by:

execute in interface Executor

drain

public final void drain()

If no other thread is running this method, run all tasks in the queue in the current thread, otherwise do nothing.

toString

public String toString()

Overrides:

toString in class Object
