CTypedPointerList...

I have class declarations like this:

class SomeClass
{
   //blah blah
};

class SomeOtherClass
{
protected:
   CTypedPtrList<CPtrList, CSomeClass*> m_Fields;
};

I want to add a member function getFields() that returns a reference to the m_Fields member variable. How should the the function be declared ?

This is not a homework problem.

Also, you might find a typedef handy to make the code more readable.

eg:

class SomeClass
{
   //blah blah
};

typedef CTypedPtrList<CPtrList, CSomeClass*> CSomeClassList;

class SomeOtherClass
{
protected:
   CSomeClassList m_Fields;
public:
   CSomeCLassList& getFields() { return m_Fields; }
   const CSomeCLassList& getFields() const { return m_Fields; }
};

NOTE: I also included a const function .. its often a good idea with access functions.  In fact, sometimes you ONLY want the const version.
