class ResizableThreadPoolScheduler

[source: scala/actors/scheduler/ResizableThreadPoolScheduler.scala]

class ResizableThreadPoolScheduler(protected val terminate : Boolean, protected val daemon : Boolean): extends java.lang.Thread with IScheduler with TerminationMonitor

This scheduler class uses a ThreadPoolExecutor to execute Actors. The scheduler attempts to shut down itself and the underlying ThreadPoolExecutor only if terminate is set to true. Otherwise, the scheduler must be shut down explicitly.

Method Summary
`def`	execute (fun : => Unit) : Unit Submits a closure for execution.
`def`	execute (task : java.lang.Runnable) : Unit Submits a `Runnable` for execution.
`def`	isActive : Boolean When the scheduler is active, it can execute tasks.

`def`	restart : Unit Resumes the execution of the scheduler if it was previously suspended using `snapshot`.
`override def`	run : Unit
`def`	shutdown : Unit Shuts down the scheduler.
`def`	snapshot : Unit Suspends the scheduler. All threads that were in use by the scheduler and its internal thread pool are terminated.
