      obj - the object to be written
      Throws:
      IOException - Any of the usual Input/Output related exceptions.
    • write

      void write(int b) throwsIOException
      Writes a byte. This method will block until the byte is actually written.
      Specified by:
      write in interface DataOutput
      Parameters:
      b - the byte
      Throws:
      IOException - If an I/O error has occurred.
    • write

      void write(byte[] b) throwsIOException
      Writes an array of bytes. This method will block until the bytes are actually written.
      Specified by:
      write in interface DataOutput
      Parameters:
      b - the data to be written
      Throws:
      IOException - If an I/O error has occurred.
    • write

      void write(byte[] b, int off, int len) throwsIOException
      Writes a sub array of bytes.
      Specified by:
      write in interface DataOutput
      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.
      IndexOutOfBoundsException - Ifoff is negative,len is negative, orlen is greater thanb.length - off
    • flush

      void flush() throwsIOException
      Flushes the stream. This will write any buffered output bytes.
      Throws:
      IOException - If an I/O error has occurred.
    • close

      void close() throwsIOException
      Closes the stream. This method must be called to release any resources associated with the stream.
