Instance Public methods

find_all(req)

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

# File ruby/lib/rubygems/resolver/set.rb, line 33
def find_all(req)
  raise NotImplementedError
end

prefetch(reqs)

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.
