find_all(req) click to toggle source

Return an array of IndexSpecification objects matching DependencyRequest req.

 
               # File rubygems/dependency_resolver/index_set.rb, line 27
def find_all req
  res = []

  name = req.dependency.name

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

  res
end

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

Called from IndexSpecification to get a true Specification object.

 
               # File rubygems/dependency_resolver/index_set.rb, line 46
def load_spec name, ver, source
  key = "#{name}-#{ver}"
  @specs[key] ||= source.fetch_spec(Gem::NameTuple.new(name, ver))
end

No prefetching needed since we load the whole index in initially.
