+ Container traits.
+
+ Unspecialized ContainerTraits has the isNotContainer typedef for SFINAE.
+ All user defined containers must supply an appropriate specialization for
+ ContinerTraits (without the typedef isNotContainer). The containers that
+ come with LuaBridge also come with the appropriate ContainerTraits
+ specialization. See the corresponding declaration for details.
+
+ A specialization of ContainerTraits for some generic type ContainerType
+ looks like this:
+
+ template <class T>
+ struct ContainerTraits <ContainerType <T> >
+ {
+ typedef typename T Type;
+
+ static T* get (ContainerType <T> const& c)
+ {
+ return c.get (); // Implementation-dependent on ContainerType
+ }
+ };

+struct ContainerTraits
+{
+ typedef bool isNotContainer;
