    #find_all(req)  
  



  

    

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


  





  
Raises:


    
  
  • 
    (NotImplementedError)

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.
