##

close()
  Closes the stream.
flush()
  Flushes the stream.
write(byte[])
  Writes an array of bytes.
write(byte[], int, int)
  Writes a sub array of bytes.
write(int)
  Writes a byte.
writeObject(Object)
  Write an object to the underlying storage or stream.

##

writeObject

      public abstract void writeObject(Object obj) throws IOException

  Write an object to the underlying storage or stream. The class that implements this interface defines how the object is written.

  Throws: IOException
    Any of the usual Input/Output related exceptions.

write

      public abstract void write(int b) throws IOException

  Writes a byte. This method will block until the byte is actually written.

  Parameters:
    b - the byte
  Throws: IOException
    If an I/O error has occurred.

write

      public abstract void write(byte b[]) throws IOException

  Writes an array of bytes. This method will block until the bytes are actually written.

  Parameters:
    b - the data to be written
  Throws: IOException
    If an I/O error has occurred.

write

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

  Writes a sub array of bytes.

  Parameters:
    b - the data to be written
    off - the start offset in the data
    len - the number of bytes that are written
  Throws: IOException
    If an I/O error has occurred.

flush

      public abstract void flush() throws IOException

  Flushes the stream. This will write any buffered output bytes.

  Throws: IOException
    If an I/O error has occurred.

close

      public abstract void close() throws IOException

  Closes the stream. This method must be called to release any resources associated with the stream.

  Throws: IOException
    If an I/O error has occurred.
