New Revision: 15618
URL: http://svn.gna.org/viewcvs/relax?rev=15618&view=rev
Log:
Fixes and clean up of the slave to master transfer mechanism for result
commands.
The master_queue_command() and master_receive_result() methods are now defined
at the Processor
level (but call raise_unimplemented()). Full epydoc docstrings and comments
have been added
everywhere. The 2 methods have now been defined for uni-processor fabric, and
simply hold the
command in a temporary variable.
