According to the latest drafts, yes. This is a recent extension, though, and not supported by most compilers. Also, there are limits on the types of things that can be member templates. I've not studied the list in detail, but I do remember that non-virtual functions are OK, virtual functions no. |> Something like: |> class A { |> public: |> A(); |> // .... |> private: |> template process(); |> // .... |> }; |> Both SunPro and Watcom give errors for such a code. |> I can't define A because T is decided upon after A is constructed. I know for a fact that the Sun compilers do not support this. (I rather suspect that they are waiting some stability in order to introduce all of the changes at once, so we only have to change our code once, and not with each release.) I'm also pretty sure that the syntax is false. I'm not even sure what you are trying to do. I presume that you want process to be a set of functions that in some way depends on the type T. In this case, the T must appear somewhere in the parameter list of the function, in order that the compiler can know which version to generate. (I think that the syntax here would be exactly the same as that of a non-member template function.) -- James Kanze Tel.: (+33) 88 14 49 00 email: kanze@gabi-soft.fr GABI Software, Sarl., 8 rue des Francs-Bourgeois, F-67000 Strasbourg, France Conseils, �tudes et r�alisations en logiciel orient� objet -- -- A la recherche d'une activit� dans une region francophone --- [ comp.std.c++ is moderated.
