- Constructor Detail
  - PipedWriter
    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:
    snk - The piped reader to connect to.
    
    Throws:
    
    IOException - if an I/O error occurs.
  - PipedWriter
    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.

    PipedReader.connect(java.io.PipedWriter), connect(java.io.PipedReader)
- Method Detail
  - connect
    public 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:
    snk - the piped reader to connect to.
    
    Throws:
    
    IOException - if an I/O error occurs.
  - write
    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.
    
    Overrides:
    
    write in class Writer
    
    Parameters:
    c - the char to be written.
    
    Throws:
    
    IOException - if the pipe is broken, unconnected, closed or an I/O error occurs.
  - write
    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.
    
    Specified by:
    
    write in class Writer
    
    Parameters:
    cbuf - the data.
    off - the start offset in the data.
    len - the number of characters to write.
    
    Throws:
    
    IOException - if the pipe is broken, unconnected, closed or an I/O error occurs.
  - flush
    public 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.
    
    Specified by:
    
    flush in interface Flushable
    
    Specified by:
    
    flush in class Writer
    
    Throws:
    
    IOException - if the pipe is closed, or an I/O error occurs.
  - close
    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.
    
    Specified by:
    
    close in interface Closeable
    
    Specified by:
    
    close in interface AutoCloseable
    
    Specified by:
    
    close in class Writer
    
    Throws:
    
    IOException - if an I/O error occurs.
