DESCRIPTION:
|
|
Simple protocol 'log' class declaration
|
|
|
|
PUBLIC CLASSES AND METHODS:
|
|
cProtocolLog
|
|
This class stores protocol buffers in to a flat array (actually a
|
|
double-ended queue) so that they can be accessed by other objects
|
|
during the flow of normal processing. Note that the storage is
|
|
in-memory and therefore finite
|
