Detailed Description

The class RWSynchronizedDataOutputStreamImp implements a simple lock stream that can be used with data output stream. The stream locks its internal synchronization mechanism before forwarding output requests to its associated sink stream, and then unlocks the internal synchronization mechanism upon completion. The stream's internal synchronization mechanism is locked using a guard object, ensuring its proper release in the event an exception is thrown.
