### 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
    28 def redefine_method(method, &block)
    29   visibility = method_visibility(method)
    30   silence_redefinition_of_method(method)
    31   define_method(method, &block)
    32   send(visibility, method)
    33 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
    37 def redefine_singleton_method(method, &block)
    38   singleton_class.redefine_method(method, &block)
    39 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
    10 def silence_redefinition_of_method(method)
    11   if method_defined?(method) || private_method_defined?(method)
    12     # This suppresses the "method redefined" warning; the self-alias
    13     # looks odd, but means we don't need to generate a unique name
    14     alias_method method, method
    15   end
    16 end
