Imperative way:

  #include <boost/mpl/or.hpp>
  #include <boost/mpl/assert.hpp>
  #include <boost/type_traits/is_same.hpp>

  template <class T>
  struct myClass
  {
     BOOST_MPL_ASSERT((boost::mpl::or_<
         boost::is_same<T,int>
       , boost::is_same<T,float>
       , boost::is_same<T,char>
     >));

     ... // your class implementation here.
  };

to summarize my question,
is there any way i can restrict the compiler to accept only few type
names for my templated class (i.e., using standard c++ or boost)


HTH,

Ah.. Thank you, I was just thinking in the same lines. May be i should go over mpl more thoroughly.
