Instance Methods

find_all(req)

lib/rubygems/resolver/set.rb View on GitHub

          
            # File tmp/rubies/ruby-2.4.10/lib/rubygems/resolver/set.rb, line 34
def find_all req
  raise NotImplementedError
end

The find_all method must be implemented. It returns all Resolver Specification objects matching the given DependencyRequest req.

prefetch(reqs)

lib/rubygems/resolver/set.rb View on GitHub

          
            # File tmp/rubies/ruby-2.4.10/lib/rubygems/resolver/set.rb, line 46
def prefetch reqs
end

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.
