Class TopologyParser

source code

This class offers a way to interpret network topologies supplied under the form :

# Comment <these machines> : <can reach these ones>

source code

load(self, filename)
read a given topology configuration file and store the results in self._routes.

source code

_build_graph(self)
build a network topology graph according to the information we got from the configuration file.

source code

tree(self, root, force_rebuild=False)
Return a previously generated propagation tree or build it if required.

(Constructor)

source code

instance wide variables initialization

Overrides: ConfigParser.RawConfigParser.__init__

load(self, filename)

source code

read a given topology configuration file and store the results in self._routes. Then build a propagation tree.

tree(self, root, force_rebuild=False)

source code

Return a previously generated propagation tree or build it if required. As rebuilding tree can be quite expensive, once built, the propagation tree is cached. you can force a re-generation using the optionnal `force_rebuild' parameter.
