  #  - If we're the only one, no overload required
  #  - If we're one of many w/ the same name:
  #     - Find out which in the list we are
  #     - Add the number to ruby_name, unless user has renamed
  #     - Build typedef of the method and use it in the exposure

Instance Method Details

#code_path ⇒ Object

This method should return the full C++ path to the method you’re exposing

def code_path
  self.code.qualified_name
end

#write ⇒ Object

Wrap up this method making sure that overloads are properly typedef’d to keep from compiler error from unresolvable types

Thanks to Py++ for the appropriate C++ syntax for this.
