Voided Check Template
Voided Check Template - Several answers already explain the rationale. Compare vartype and typeid().name / typename. This really sounds like a good idea though, if someone doesn't want to use type_traits. Jessen already mentioned in the comments , you have to look this oid up in your ad to get the template name. 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. // should return true istemplate();
Compare vartype and typeid().name / typename. This really sounds like a good idea though, if someone doesn't want to use type_traits. 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. Was wondering if it's possible to have a template function that can branch depending on whether the type is derived from a particular class. 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:
Here's roughly what i'm thinking: 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: I need a way to check if a templated class's type is void. @gmannickg it's item 66 of sutter.
Compare vartype and typeid().name / typename. Was wondering if it's possible to have a template function that can branch depending on whether the type is derived from a particular class. 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.
Jessen already mentioned in the comments , you have to look this oid up in your ad to get the template name. Template <typename target_type, typename start_function_type, typename end_function_type> 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..
To add to those answers, the specification says (c++11 §8.3.5[dcl.func]/4): Was wondering if it's possible to have a template function that can branch depending on whether the type is derived from a particular class. I need a way to check if a templated class's type is void. @gmannickg it's item 66 of sutter & alexandrescu's coding standards: // should return.

Voided Check Template - Here's roughly what i'm thinking: 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? 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'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: // should return true istemplate();

Jessen already mentioned in the comments , you have to look this oid up in your ad to get the template name. // should return true istemplate(); 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.
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.
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. 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): Template <typename target_type, typename start_function_type, typename end_function_type>
