Re: [cdt-dev] what exactly is stored in the index?

[Sergey Prigogin <eclipse.sprigogin@xxxxxxxxx>]

Lets consider a case involving template specialization:

template <typename T> class A {};

template <> class A<int> { A(const char* s) {} }

void f()
{
         typedef int Int;
         A<Int> a("");
}

'A' in 'A<Int> a("");' is a reference to template class A and a("") contains an implicit reference to constructor A<int>::A(const char*). It looks like these are the only two references that we need for search and rename refactoring. The reference to the template specialization A<int> is not needed since rename refactoring does not need it and C/C++ search cannot search for specializations.

I see. But given that the local type 'Int' is a typedef for the global
type 'int', shouldn't a search for 'A<int>' find the 'A<Int>' as well?

Thanks,
