# 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
