Voided Check Template
Voided Check Template - I'm trying to detect whether a type (or more precisely, an identifier as technically a template is not a type) is a template or not, eg to have a function istemplate which behaves the following way: Hmm because i had a large portion of same code until the 'specification' part. To add to those answers, the specification says (c++11 §8.3.5[dcl.func]/4): Compare vartype and typeid().name / typename. Several answers already explain the rationale. It does contain the extension certificate template information though, but i cannot parse a name from it, because it does only contain the oid of the template.
Compare vartype and typeid().name / typename. Hmm because i had a large portion of same code until the 'specification' part. If you're writing a function template, prefer to write it as a single function template that should never be specialized or overloaded, and implement the function template entirely in terms of a. I'm trying to detect whether a type (or more precisely, an identifier as technically a template is not a type) is a template or not, eg to have a function istemplate which behaves the following way: @gmannickg it's item 66 of sutter & alexandrescu's coding standards:
It shows is_convertible is false from string_view to string.however, looking at how the stl does it in the header, they define a template typedef (of type _stringviewish) using _is_string_view_ish = enable_if_t<conjunction_v<is_convertiable<const _stringviewish&, basic_string_view<_elem, _traits>>, negation<is_convertable<const _stringviewish&, const. Was wondering if it's possible to have a template function that can branch depending on whether the type is derived from a particular.
You can use overloading, but if a large part of the code would work for any type, you might consider extracting the differing part into a separate function and overload that.

Jessen already mentioned in the comments , you have to look this oid up in your ad to get the template name. Compare vartype and typeid().name / typename. Template <typename target_type, typename start_function_type, typename end_function_type> Hmm because i had a large portion of same code until the 'specification' part. // should return true istemplate();
Like someone mentioned the main logic can be done in a different function, which accepts an extra flag to indicate the type, and this specialized declaration can just set the flag accordingly and directly pass on all the other arguments without touching anything.

I need a way to check if a templated class's type is void.

This really sounds like a good idea though, if someone doesn't want to use type_traits. How to check if template type is of another template type?
