Constructor Details

#initialize(wrapper, rank) ⇒ Candidate

Returns a new instance of Candidate.

Parameters:

    The associated ‘Pry::WrappedModule` instance that owns the candidates.

  • rank (Fixnum)

    The rank of the candidate to retrieve. Passing 0 returns ‘primary candidate’ (the candidate with largest number of methods), passing 1 retrieves candidate with second largest number of methods, and so on, up to ‘Pry::WrappedModule#number_of_candidates() - 1`
