I want to have several overloaded, global to_string() functions that take some type T and convert it to its string representation.For the general case, I want to be able to write:
Using SFINAE, i can detect wether a given class has a certain member function. But what if i want to test for inherited member functions?
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical andc开发者_运维百科annot be reasonably answered in its current form.
I\'ve read the various authorities on this, include Dewhurst and yet haven\'t managed to get anywhere with this seemingly simple question.
The following code shows an SFINAE implementation to check whether a type (basically a class) contains a member function member_func at compile time.
The following code of mine should detect whether T has begin and end methods: template <typename T>
This question already has answers here: Closed 12 years ago. Possible Duplicate: Is it possible to write a C++ template to check for a function's existence?
In code: template<class T> struct is_builtin { enum {value = 0}; }; template<> struct is_builtin<char>
compiling with GCC i get always false from the following code. I believe this is a compiler bug, but someone may know better.
I need a easy way to assert inside a template that a template parameter implements a method (or one of its parent classes). I\'ve read Concept check library but is hard to find an easy example to do s
