That works for me. I also looked at miscws/noxinfows.py, which seems to
do some of the things I wanted.
I am trying to modify noxinfows.py to return topology. I got a handle
for pytopology with
self.pytop = self.resolve(pytopology)
Later, when the GET request comes, I am calling the function I wrote
below
def _get_nox_topology(self, request, arg):
try:
return simplejson.dumps(self.pytop.XXXXXXXXXXXXXXXXX)
except Exception, e:
return self.err(Failure(), request, "_get_topology",
"Could not retrieve topology")
Now, I don't know how to access the pytopology functions (XXXXXXXXXXXX
part). For example, the get_outlinks() function takes two arguments, but
in the C++ file, I didn't find any comments on what to pass here.
In the manual, there are just a few notes about the topology module,
grepping through the whole source tree, I didn't find any examples of
using pytopology (may be I am missing something).
Any help would be great.
Thanks,
Pradeep
