c++ - How to avoid defining the whole template class in header file -

i have class this:

template <typename t> class c { public:     c(t t): t{t} {}     void publicmethoda() { privatemethoda(); }     void publicmethodb() {}     void publicmethodc() {}     // ...  private:     void privatemethoda() { t.call(); /* 1 place uses t member */ }     void privatemethodb() {}     // ...      t t; }; 

in example need template field t in 1 place (in privatemethoda) , forces me define each method in header file (but not use t member). how can avoid this? have ideas?

you can put not depend on t in base class , inherit it. anyhow, fact class template, has many methods not depend on template parameter suggests putting stuff inside single class better belongs seperate ones.
