put template member function .cpp file

[Z.L]

Hi all,

 

As we know, if we use the template member function we need to put it in header file, for example

//in test.hpp

template<typename Dtype>

class A{

     public:

        A(Dtype a, Dtype b)

};

A<Dtype>::A(Dtype a,Dtype b){

.....

}

 

if we did not put the definiation in the header file, it is likely to get linker error. But when I can caffe code, especially, src/caffe/layers.cpp and include/caffe/layers.hpp, the declaration and definition of template member function in .hpp and .cpp files, how can it be possible?

 

Does anyone have same concern? or anyone has any thoughts on this?
