Hi,
I have a template class with 6 template arguments as :
template
class TreeImpl {};
I need to write partial specializations for the cases n=2, n=3, for 2 cases of rtype, 2 cases of qtype and 3 cases of vtype,
therefore I will write 2*2*2*3 = 24 partial specializations.
Any fully specialized template instance should be a singleton.
I would like to find a way to store any instanciated full specialization in some common list, so that in other parts of the code,
i can deal with the various singletons without having to write actual arguments n,rtype,qtype and vtype.
I thought of having all these templates inherit from a template base class
template
class TreeImplBase;
Each specialization of these holds a
static std::map< boost::tuple, const TreeImplBase* >;
which contains the list of the derived template classes.
Any comments are appreciated,
Perhaps this is a known design pattern,
perhaps there is an easier way of doing this,
perhaps there is a boost library which helps with this,
regards,
