Methods

  • PipedWritertop

    public PipedWriter()
    Creates a piped writer that is not yet connected to a piped reader. It must be connected to a piped reader, either by the receiver or the sender, before being used.

  • PipedWritertop

    public PipedWriter(PipedReader snk) throws IOException
    Creates a piped writer connected to the specified piped reader. Data characters written to this stream will then be available as input from snk.
    Parameters:
    @param snk The piped reader to connect to.
    Exceptions:
    @exception IOException if an I/O error occurs.

  • closetop

    public void close() throws IOException
    Closes this piped output stream and releases any system resources associated with this stream. This stream may no longer be used for writing characters.
    Exceptions:
    @exception IOException if an I/O error occurs.
    Specified by:
    close from Closeable
    Override hierarchy:
    close from Writer

  • connecttop

    public synchronized void connect(PipedReader snk) throws IOException
    Connects this piped writer to a receiver. If this object is already connected to some other piped reader, an IOException is thrown.

    If snk is an unconnected piped reader and src is an unconnected piped writer, they may be connected by either the call: 

     src.connect(snk)
    or the call: 
     snk.connect(src)
    The two calls have the same effect.
    Parameters:
    @param snk the piped reader to connect to.
    Exceptions:
    @exception IOException if an I/O error occurs.

  • flushtop

    public synchronized void flush() throws IOException
    Flushes this output stream and forces any buffered output characters to be written out. This will notify any readers that characters are waiting in the pipe.
    Exceptions:
    @exception IOException if the pipe is closed, or an I/O error occurs.
    Specified by:
    flush from Flushable
    Override hierarchy:
    flush from Writer

  • writetop

    public void write(int c) throws IOException
    Writes the specified char to the piped output stream. If a thread was reading data characters from the connected piped input stream, but the thread is no longer alive, then an IOException is thrown.

    Implements the write method of Writer.

    Parameters:
    @param c the char to be written.
    Exceptions:
    @exception IOException if the pipe is broken, unconnected , closed or an I/O error occurs.
    Override hierarchy:
    write from Writer

  • writetop

    public void write(char[] cbuf, int off, int len) throws IOException
    Writes len characters from the specified character array starting at offset off to this piped output stream. This method blocks until all the characters are written to the output stream. If a thread was reading data characters from the connected piped input stream, but the thread is no longer alive, then an IOException is thrown.
    Parameters:
    @param cbuf the data.
    @param off the start offset in the data.
    @param len the number of characters to write.
    Exceptions:
    @exception IOException if the pipe is broken, unconnected , closed or an I/O error occurs.
    Override hierarchy:
    write from Writer
