Class PipedOutputStream

Constructor Detail

• PipedOutputStream

  public PipedOutputStream(PipedInputStream snk)
                    throws IOException

  Creates a piped output stream connected to the specified piped input stream. Data bytes written to this stream will then be available as input from snk.

  Parameters:

  snk - The piped input stream to connect to.

  Throws:

  IOException - if an I/O error occurs.

• PipedOutputStream

  public PipedOutputStream()

  Creates a piped output stream that is not yet connected to a piped input stream. It must be connected to a piped input stream, either by the receiver or the sender, before being used.

  See Also:

  PipedInputStream.connect(java.io.PipedOutputStream), connect(java.io.PipedInputStream)

Method Detail

• connect

  public void connect(PipedInputStream snk)
               throws IOException

  Connects this piped output stream to a receiver. If this object is already connected to some other piped input stream, an IOException is thrown.

  If snk is an unconnected piped input stream and src is an unconnected piped output stream, 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 input stream to connect to.

  Throws:

  IOException - if an I/O error occurs.

• write

  public void write(int b)
             throws IOException

  Writes the specified byte to the piped output stream.

  Implements the write method of OutputStream.

  Specified by:

  write in class OutputStream

  Parameters:

  b - the byte to be written.

  Throws:

  IOException - if the pipe is broken, unconnected, closed, or if an I/O error occurs.

• write

  public void write(byte[] b,
           int off,
           int len)
             throws IOException

  Writes len bytes from the specified byte array starting at offset off to this piped output stream. This method blocks until all the bytes are written to the output stream.

  Overrides:

  write in class OutputStream

  Parameters:

  b - the data.

  off - the start offset in the data.

  len - the number of bytes to write.

  Throws:

  IOException - if the pipe is broken, unconnected, closed, or if an I/O error occurs.

• flush

  public void flush()
             throws IOException

  Flushes this output stream and forces any buffered output bytes to be written out. This will notify any readers that bytes are waiting in the pipe.

  Specified by:

  flush in interface Flushable

  Overrides:

  flush in class OutputStream

  Throws:

  IOException - if 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 bytes.

  Specified by:

  close in interface Closeable

  Specified by:

  close in interface AutoCloseable

  Overrides:

  close in class OutputStream

  Throws:

  IOException - if an I/O error occurs.
