### Public Instance Methods

redefine_method(method, &block) click to toggle source

Replaces the existing method definition, if there is one, with the passed block as its body.

    # File lib/dbus/core_ext/module/redefine_method.rb, line 27
    def redefine_method(method, &block)
      visibility = method_visibility(method)
      silence_redefinition_of_method(method)
      define_method(method, &block)
      send(visibility, method)
    end

redefine_singleton_method(method, &block) click to toggle source

Replaces the existing singleton method definition, if there is one, with the passed block as its body.

    # File lib/dbus/core_ext/module/redefine_method.rb, line 36
    def redefine_singleton_method(method, &block)
      singleton_class.redefine_method(method, &block)
    end

silence_redefinition_of_method(method) click to toggle source

Marks the named method as intended to be redefined, if it exists. Suppresses the Ruby method redefinition warning. Prefer redefine_method where possible.

    # File lib/dbus/core_ext/module/redefine_method.rb, line 9
    def silence_redefinition_of_method(method)
      if method_defined?(method) || private_method_defined?(method)
        # This suppresses the "method redefined" warning; the self-alias
        # looks odd, but means we don't need to generate a unique name
        alias_method method, method
      end
    end
