Hello,I defined a class using GenLinearHierarchy.But when I try to use Field with it, I got compiling failed.
The explain of Field says that it defines for GenScatterHierarchy.But Modern C++ Design says Field has
8 overloading forms and could be used with GenLinearHierarchy.
Please tell me how to get object reference within a GenLinearHierarchy class object?Thanks
