Can anyone briefly explains me what a class helper is
I think class helper it some functions/procedures take the first params as the class (that you want to make helper for it), but the fist param (the class) passed as Class of this method.
function (MyClass:TMyClass; param2:TParam2); but you can use it as MyClass.function (param2:TParam2); Nothing else, so it make as class helper as mentioned in the help of Delphi, it is not multi inheritance.
