I have a function declaration like this in a template class.
template <class T> class CElement

public:
template <class Y> bool _internal_less (CElement<Y> const& rhs) const;

And following is the function defination...
template <class T, class Y> inline
bool CElement <T>::_internal_less (CElement<Y> const& rhs) const
{
return iCount < rhs.iCount;
}
when i compile it using , g++ , it gives error ....
"prototype for `bool CElement<T>::_internal_less(const CElement<Y>&)
const' does not match any in class `CElement<T>'"
couple of suggestions...
you can't define an inline function out of line ... also you need two
separate template<> parameter definitions in your out of line
definition, one for the class template and one for the template member
function. With such a simple function I'd use an inline definition
especially if you have profiling data to backup your need for inlining
the function:
template <class T> class CElement
{
public:
template <class Y>
bool _internal_less (CElement<Y> const& rhs) const
{
return iCount < rhs.iCount;
}
};
If you want an out of line definition then something like this should
work:
template <class T>
template <class Y>
bool CElement <T>::_internal_less (CElement<Y> const& rhs) const
{
return iCount < rhs.iCount;
}
