base_type.cpp

template <class Format, class Dispatch>
mesh<Format, Dispatch>::mesh(std::string const &name) :
    resource< mesh<Format, Dispatch> >(name),
    _nbIndices(0) {
}

// after a base_type idiom ...

template <class Format, class Dispatch>
mesh<Format, Dispatch>::mesh(std::string const &name) :
    mesh::resource_base_type(name), // even mesh::base_type(name) :)
    _nbIndices(0) {
}

// win :)
