Singleton with parameters in ABAP

Former Member — Fri, 04 Jan 2019 21:05:15 GMT

Hi all

I would like to know, how can I create a singleton class pattern with parameters?

In other programming language I can overload the class-constructor but since in ABAP overloading a method is not possible, how can I pass the parameters?

Thanks

Hi Anujit,

Why do you want to pass a parameter to the singleton class constructor ??. Can you please elaborate it ??..

This has already been answered several times in the forum: use optional parameters to mimic the overloading. Be careful when you use the term "class constructor", it has a special meaning in ABAP (it can't have any parameter), so I guess you mean simply "constructor".

A class-constructor in ABAP is like a static class initialiser in Java.
