YiIsBaseOf< BASE, DERIVED > Class Template Reference

Detailed Description

template<typename BASE, typename DERIVED>
class YiIsBaseOf< BASE, DERIVED >

Template trait utility that checks if a specific type is a base of another type. This trait can be used in templated functions and classes to perform static assertions, or in template specializations to enable/disable specific implementations.

Note

CV qualifiers are ignored. For example, 'const CYISceneNode' is considered to be a base of 'CYISceneView'.

A base of a base of a type is considered to be a base of that type. This function does not distinguish between direct bases and bases of bases.

For the purposes of this function, a type is considered to be a base of itself. This is to implement an 'is a' check, rather than a true 'does this type have this base' check.

void is not considered a base of any type, and is considered to have no bases.

Example:

template<typename T>
static bool IsSceneNodeType()
{
    bool bIsSceneNode = YiIsBaseOf<CYISceneNode, T>::value;
    return bIsSceneNode;
}

#include <utility/YiTypeTraits.h>
