“invalid use of incomplete type” error with partial template specialization

by

You can’t partially specialize a function. If you wish to do so on a member function, you must partially specialize the entire template (yes, it’s irritating). On a large templated class, to partially specialize a function, you would need a workaround. Perhaps a templated member struct (e.g. template <typename U = T> struct Nested) would work. Or else you can try deriving from another template that partially specializes (works if you use the this->member notation, otherwise you will encounter compiler errors).
