equalizer
Module to define equality, equivalence and inspection methods
Examples
class GeoLocation
include Equalizer.new(:latitude, :longitude)
attr_reader :latitude, :longitude
def initialize(latitude, longitude)
@latitude, @longitude = latitude, longitude
end
end
point_a = GeoLocation.new(1, 2)
point_b = GeoLocation.new(1, 2)
point_c = GeoLocation.new(2, 2)
point_a.inspect # => "#<GeoLocation latitude=1 longitude=2>"
point_a == point_b # => true
point_a.hash == point_b.hash # => true
point_a.eql?(point_b) # => true
point_a.equal?(point_b) # => false
point_a == point_c # => false
point_a.hash == point_c.hash # => false
point_a.eql?(point_c) # => false
point_a.equal?(point_c) # => false
