A hint run by the resolver to allow the Set to fetch data for DependencyRequests reqs.
Prefetches reqs in all sets.
Prefetches specifications from the git repositories in this set.
The prefetch method may be overridden, but this is not necessary. This default implementation does nothing, which is suitable for sets where looking up a specification is cheap (such as installed gems).
When overridden, the prefetch method should look up specifications matching reqs.
The silent download reporter does not display filename or care about filesize because it is silent.
Tells the download reporter that the file_name is being fetched. The other arguments are ignored.
Expire memoized instance variables that can incorrectly generate, replace or miss files due changes in certain attributes used to compute them.
Returns the inverse of the eigenvector matrix V
True if the gems in the system satisfy dependency.
Prefix and suffix the program filename the same as ruby.
