In reply to lalithjithan:
The function can return the “class handler” (can’t return a class, I don’t know what you mean to return a “class” in function):
function my_class get_object();
my_class handler = new;
// Do something
return handler;
endfunction
// To use
my_class handler = get_object();
However, you can also pass the object handler to function and modify inside the function:
function void get_object(my_class handler_copy);
// Do something
endfunction
// To use
my_class handler_original = new;
get_object(handler_original);
Why it works? When you pass object handler to a function by value, the object handler will be copied (stored in stack). We have 2 handlers (handler_original and handler_copy) which point to same memory location where the object is created. When you modify the “handler_copy” in function, the “handler_original” is also changed.
