Instance Method Details

#find_all(req) ⇒ Object

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

Raises:

  • (NotImplementedError)

# File 'lib/rubygems/resolver/set.rb', line 33

def find_all(req)
  raise NotImplementedError
end

#prefetch(reqs) ⇒ Object

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.

end

#remote? ⇒ Boolean

When true, this set is allowed to access the network when looking up specifications or dependencies.

Returns:

  • (Boolean)
