#initialize(class_name:, method_name:, args: [], kwargs: {}) ⇒ Callback

Note:

if the class implements the method_name, the message will be sent to the class with the args and kwargs.

otherwise, an instance of the class will be created and the message will be sent to the instance. in this case, the args and kwargs will be passed to the initializer.

Parameters:

  • class_name (String) —

    the name of the class that will receive the callback

  • method_name (String) —

    the name of the method that will be called

  • args (Array) (defaults to: []) —

    the positional arguments to be passed to the method (optional)

  • kwargs (Hash) (defaults to: {}) —
