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