how to get a tab through the tab's attribute text in TabPane in javafx? - javafx

Question

I want get a tab through the tab's attribute text, but I cannot find a native method. So I writed a class to implement the purpose.
Question:
- I want to know if there is a native method for that purpose?
- Is there a better implementation?
Thanks!
