Detailed Description
template<typename T>
class TAttribute< T >
Class of an attribute that holds data of type T.
This class is the templated derivative of CAttribute that provides the container for most attributes you will come across. The value is stored read-only. It implements implements the abstract methods typedescr, do_as_string, do_is_equal, do_is_less For this type, is_equal returns true if the other attribute has the same type and holds the same value. is_less returns true of either the type is equal and the value is less, or with different types if a string-compare strcmp between the type descriptions returns -1.
