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
