Detailed Description

Binary buffer output class.

This class is used to write data to a binary buffer. The data in the buffer is big-endian. If the host nachine is little-endian, the data is byte-swapped. Output is done from the primary node only.

Buffers need to be opened before any of the write methods are used

The write methods are also wrapped by externally defined functions and << operators,
