Returns: str: the URL of the virtual feed, or None

Since: 0.49

get_package_impls(self, distro)

source code

Find the best <pacakge-implementation> element(s) for the given distribution.

Parameters:

distro (distro.Distribution) - the distribution to use to rate them

Returns: [str]

a list of tuples for the best ranked elements

Since: 0.49

repr(self)
(Representation operator)

source code
