Detailed Description

template<typename T>
class ClassID_traits< T >

Default, invalid implementation of ClassID_traits.

a traits class that associates a CLID to a type T It also detects whether T inherits from Gaudi DataObject

The CLASS_DEF macro specialises this class in order to provide functional descriptions of the EDM classes. This default class is non-functional on purpose, to generate compile-time errors in case some code tries using CLID information on a type that doesn't provide one.

This default specialization just gives errors.

Normally, this will get specialized by the CLASS_DEF macro.
