Method Detail

run

boolean run()
     throws IOException

Run the logic. This method allows throwing an interrupted exception on wakeup, but the implementation does not have to. It is preferred to finish the work elegantly and return a boolean to indicate whether all the jobs have been done or more invocation is needed.

Returns:

whether the runnable has successfully finished running.

Throws:

IOException - when the performed I/O operation fails.

wakeUp

void wakeUp()

Wake up the running thread.
