a class sharing the public struct of another class

[Victor Hannak]

I have a class like this:
<LarryClass.h >
class LarryClass {

public:
struct MoeLinkedListSt ruct {
LarryClass *Larry;
float MoeValue;
MoeLinkedListSt ruct *NextMoe;
};
LarryClass();
~LarryClass();
void Eval(float Value, MoeLinkedListSt ruct *&MoePtr);

private:
.....
}

I also have another class wherein I would like to be able to dynamically
create a new MoeLinkedListSt ruct like this:
<MoeClass.h>
#include "LarryClass .h"

<MoeClass.cpp >
MoeLinkedListSt ruct *MoePtr = new MoeLinkedListSt ruct;
LarryClass *Larry = new LarryClass;
Larry->Eval(0,MoePtr) ;

So the question is this: how do I make the MoeLinkedListSt ruct visible to
LarryClass? Since the struct is defined in the public area of LarryClass,
shouldn't the above code work? Am I just missing something small? I can't
really put the structure definition into a different file, because it has a
LarryClass variable in it, so LarryClass must already be defined. What else
could I do here? By the way, the intent here is for the Eval function in
LarryClass to be able to modify MoePtr to point to a different Moe, and then
pass that back up to the MoeClass.

Thanks, Vic

This should work.

LarryClass::Moe LinkedListStruc t *MoePtr = new
LarryClass::Moe LinkedListStruc t;

Not true, because MoeLinkedListSt ruct only has a pointer to LarryClass you
could use a forward declaration.

class LarryClass; // forward declaration

struct MoeLinkedListSt ruct {
LarryClass *Larry;
float MoeValue;
MoeLinkedListSt ruct *NextMoe;
};

This will compile without LarryClass being fully defined.
