Support for the Ruby 2.1 series ended on March 31 2017. See here for details.
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 20 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 32 def prefetch reqs end
