Constructor Details

#initialize(name) ⇒ WrapperBase

The initialize method sets up the instance name by converting the input to a string representation.

This method handles different input types by converting them to a string, prioritizing to_str over to_sym and falling back to to_s if neither is available.

Parameters:

  • name (Object) —

    the input name to be converted to a string
