Examples of java.io.PipedOutputStream

java.io.PipedOutputStream
A piped output stream can be connected to a piped input stream to create a communications pipe. The piped output stream is the sending end of the pipe. Typically, data is written to a PipedOutputStream object by one thread and data is read from the connected PipedInputStream by some other thread. Attempting to use both objects from a single thread is not recommended as it may deadlock the thread. The pipe is said to be broken if a thread that was reading data bytes from the connected piped input stream is no longer alive. @author James Gosling @version 1.28, 06/07/06 @see java.io.PipedInputStream @since JDK1.0
