Get information about the given package.

source code

int | None

get_score(self, disto_name)
Indicate how closely the host distribution matches this one.

source code

fetch_candidates(self, master_feed)
Collect information about versions we could install using the distribution's package manager.

(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

get_package_info(self, package, factory)

source code

Get information about the given package. Add zero or more implementations using the factory (typically at most two will be added; the currently installed version and the latest available).

Parameters:

package - package name (e.g. "gimp")
factory - function for creating new DistributionImplementation objects from IDs

Overrides: Distribution.get_package_info

(inherited documentation)

get_score(self, disto_name)

source code

Indicate how closely the host distribution matches this one. The <package-implementation> with the highest score is passed to Distribution.get_package_info. If several elements get the same score, get_package_info is called for all of them.

Parameters:

distribution - a distribution name

Returns: int | None

an integer, or None if there is no match at all

Overrides: Distribution.get_score

(inherited documentation)

fetch_candidates(self, master_feed)

source code

Collect information about versions we could install using the distribution's package manager. On success, the distribution feed in iface_cache is updated.

Returns:: a tasks.Blocker if the task is in progress, or None if not
Overrides: Distribution.fetch_candidates: (inherited documentation)
