Return an array of IndexSpecification objects matching DependencyRequest req.

# File lib/rubygems/dependency_resolver.rb, line 210
def find_all(req)
  res = []

  name = req.dependency.name

  @all[name].each do |uri, n|
    if req.dependency.match? n
      res << IndexSpecification.new(self, n.name, n.version,
                                    uri, n.platform)
    end
  end

  res

load_spec(name, ver, source) click to toggle source

Called from IndexSpecification to get a true Specification object.

# File lib/rubygems/dependency_resolver.rb, line 234
def load_spec(name, ver, source)
  key = "#{name}-#{ver}"
  @specs[key] ||= source.fetch_spec(Gem::NameTuple.new(name, ver))
end
