This class is an OutputStream that implements one half a pipe and is useful for communication between threads. A PipedOutputStream must be connected to a PipedInputStream, which may be specified when the PipedOutputStream is created or with the connect( ) method. Data written to the PipedOutputStream is available for reading on the PipedInputStream. See OutputStream for information on the low-level methods for writing data to a PipedOutputStream. A FilterOutputStream can provide a higher-level interface for writing data to a PipedOutputStream.
