PipedWriter is a character output stream that writes characters to the PipedReader character input stream to which it is connected. PipedWriter implements one half of a pipe and is useful for communication between two threads of an application. A PipedWriter cannot be used until it is connected to a PipedReader object, which may be passed to the PipedWriter( ) constructor or to the connect( ) method. PipedWriter inherits most of the methods of its superclass. See Writer for more information. PipedWriter is the character-stream analog of PipedOutputStream.
