Overview

::Gem::Resolver sets are used to look up specifications (and their dependencies) used in resolution. This set is abstract.

Instance Attribute Summary

  • #errors rw

    Errors encountered when resolving gems.

  • #prerelease rw

    When true, allows matching of requests to prerelease gems.

  • #remote rw

    Set to true to disable network access for this set.

Instance Method Details

#find_all(req)

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

Raises:

  • (NotImplementedError)
[ GitHub ]

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

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.

# File 'lib/rubygems/resolver/set.rb', line 45
