Method Summary synchronized  void cleanup()      Cleans up the free and busy threads. public synchronized  void exitWhenBusyThreadsDone()      public  int getBusyThreads()      synchronized  WorkThread getFreeThread()      Gets a free thread from the free thread pool.  void init()      Initializes the instance. synchronized  void releaseThread(WorkThread thread)      Release the thread to the free pool. public  void setLogger(String logFile)      Sets the log file. public  void setMaxThreads(int count)      Sets the max threads. public  void setMinThreads(int count)      Sets the minimum threads.  void start()      Start the free threads. synchronized  void stop()      Stops the free and busy threads. Constructor Detail WorkThreadPool WorkThreadPool(int minThreadCount, int maxThreadCount)(Code) Creates a new instance of WorkThreadPool. Parameters:   minThreadCount - - minimum thread limit Parameters:   maxThreadCount - - maximum thread limit WorkThreadPool WorkThreadPool()(Code) Creates a new instance of WorkThreadPool. Method Detail cleanup synchronized void cleanup()(Code) Cleans up the free and busy threads. throws:   IllegalStateException - exception. exitWhenBusyThreadsDone public synchronized void exitWhenBusyThreadsDone()(Code) getBusyThreads public int getBusyThreads()(Code) Returns the count of threads in busy thread pool int count of number of busy threads getFreeThread synchronized WorkThread getFreeThread()(Code) Gets a free thread from the free thread pool. a worker thread instance if a free thread exists; otherwisenull. throws:   IllegalStateException - when the thread pool is not running. init void init()(Code) Initializes the instance. throws:   IllegalStateException - releaseThread synchronized void releaseThread(WorkThread thread)(Code) Release the thread to the free pool. This method is used by worker threads to notify that it has completed processing its command. Parameters:   thread - - worker thread instance. throws:   IllegalStateException - throws:   NoSuchElementException - exception setLogger public void setLogger(String logFile)(Code) Sets the log file. Parameters:   logFile - log file. setMaxThreads public void setMaxThreads(int count)(Code) Sets the max threads. Parameters:   count - max threads. setMinThreads public void setMinThreads(int count)(Code) Sets the minimum threads. Parameters:   count - min threads. start void start()(Code) Start the free threads. throws:   IllegalStateException - stop synchronized void stop()(Code) Stops the free and busy threads. throws:   IllegalStateException - exception.
