Method Detail

• free

  void free​(int reserve,
            int size)
     throws java.io.IOException

  Free at least some number of bytes of space in the byte array. If no reserve is specified, this call may write all data up to the current offset to the output stream, and if necessary will replace the byte array with a larger array. If a reserve is specified, only data up to the reserve will be written, and any remaining data will be moved down to the start of the (possibly new) byte array on return. Both IByteBuffer.getBuffer() and IByteBuffer.getOffset() must always be called again before any further use of the buffer.

  Parameters:

  reserve - offset of data to be preserved in buffer (nothing preserved if greater than or equal to current offset)

  size - desired number of bytes

  Throws:

  java.io.IOException

• flush

  void flush()
      throws java.io.IOException

  Empty the buffer. Writes all data from the buffer to the output stream, resetting the offset to the logical start of the buffer (which may not be offset zero, since implementations may add some sort of header). This method is guaranteed not to replace the byte array, but IByteBuffer.getOffset() must always be called again before any further use of the buffer.

  Throws:

  java.io.IOException
