All Implemented Interfaces:

Callable

public class TimedCallable

extends ThreadFactoryUser

implements Callable

TimedCallable runs a Callable function for a given length of time. The function is run in its own thread. If the function completes in time, its result is returned; otherwise the thread is interrupted and an InterruptedException is thrown.

Note: TimedCallable will always return within the given time limit (modulo timer inaccuracies), but whether or not the worker thread stops in a timely fashion depends on the interrupt handling in the Callable function's implementation.

This class was taken from the util.concurrent package written by Doug Lea. See http://gee.cs.oswego.edu/dl/classes/EDU/oswego/cs/dl/util/concurrent/intro.html for an introduction to this package.
