Class Overview
An output stream that also maintains a checksum of the data being
written. The checksum can then be used to verify the integrity of
the output data.

wait()
Causes the current thread to wait until another thread invokes the
notify() method or the
notifyAll() method for this object. |
|
final
void
|
wait(long timeout, int nanos)
Causes the current thread to wait until another thread invokes the
notify() method or the
notifyAll() method for this object, or
some other thread interrupts the current thread, or a certain
amount of real time has elapsed. |
|
final
