class ThreadPool extends AnyRef

A thread pool wrapper, provide some helper functions for multi-threading

TODO TreadPool will give 2-version of thread pool, one uses scala version (invokeAndWait), another is provided to Java (invokeAndWait2). The design is weird. We should refactor this class later.

    Use java future to execute the tasks.

    Use java future to execute the tasks. It will be blocking until tasks completed. If any task throws an exception, it will throw that exception in caller.

    T

    return type of tasks

    tasks

    task sequence. each task's return type is T

    timeout

    the maximum time to wait

    timeUnit

    the time unit for the timeout

    returns

    a sequence of Futures representing the tasks.
