Equality comparison allowing subclasses

Parameters:

  • other (Object) —

    object to compare

Returns:

  • (Boolean) —

    true if other is_a? same class with equal attributes

    cmp?(:==, other)
end

end

#eql?(other) ⇒ Boolean

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Strict equality requiring exact class match

Parameters:

  • other (Object) —

    object to compare
