g++ typedef

Hi everyone

I have some declaration in public: section of one class like this...

----------------------------------
file "a.h"
----------------------------------

template<class T> class example
{
public:
typedef std::vector <T*> TMem;
typedef typename TMem::iterator TMemIter;
typedef typename TMem::const_iterator TMemConIter;
typedef typename TMem::size_type TMemSize;
};


-------------------------------------------------
file "b.h"
---------------------------------------------------

#include "a.h"
.............
..............
func()
{
for (TMemConIter iterMemb = iMem.begin (); iterMemb != iMem.end (); iterMemb++)

}
........
........
..........
i compile this with g++ compiler and gets error

`TMemConIter' undeclared (first use this function)"

Can anybody help please ?

TMemConIter is a type inside the scope of class example
so you can access it only using class name :: typedef name


like example<int>::TMemConIter
