#initialize(obj, name, modul) ⇒ MethodWrapper

The initialize method sets up a new instance with the specified object, method name, and module flag.

This method creates and configures a new instance by storing the method object and its description, handling both instance methods and regular methods based on the module flag parameter.

Parameters:

  • obj (Object) —

    the object from which to retrieve the method

  • name (String) —

    the name of the method to retrieve

  • modul (TrueClass, FalseClass) —

    flag indicating whether to retrieve an instance method
