Resolver sets are used to look up specifications (and their dependencies) used in resolution. This set is abstract.
The find_all method must be implemented. It returns all Resolver Specification objects matching the given DependencyRequest req.
# File rubygems/resolver/set.rb, line 34
def find_all req
raise NotImplementedError
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.
# File rubygems/resolver/set.rb, line 46
def prefetch reqs
end
