template
struct SomeType
{
int SomeID;
T* Data;
}
(C++) Working with a non-typed template?
Suppose i have a template like so:
Could I write a function that takes a SomeType instead of a SomeType<> and works with it like that?
No. Declaring a SomeType template doesn''t mean ''plain'' SomeType exists.
Actually, now that I think of it, could I write a templatized function and just use the template class as the SomeType class type to achieve the same thing?
Yes. Either
template <class T> int Func( T arg );
or
template <class T> int Func( SomeType<T> arg );

You could also put SomeID into a non-templated base class, e.g.:
struct SomeTypeBase { int SomeID; };template <class T> struct SomeType : public SomeTypeBase{ T* Data;};

I don''t think anybody knows...
//Just wondering, but why isn''t this typdef legal????:typedef delete delete_the_thing_pointed_to_by;int* ip = new int;delete_the_thing_pointed_to_by ip;I don''t think anybody knows...
i thought typedef only applied to data types(ie. int, float, double, char, struct, class) . not keywords (ex. delete, new, if, else, etc).
delete is an operator, not a type. [ Google || Start Here || ACCU || STL || Boost || MSDN || GotW || CUJ || MSVC++ Library Fixes || BarrysWorld || E-Mail Me ]
