Detailed Description

template<typename T_BaseType, typename T_BufferType = const T_BaseType, typename T_VectorType = const std::vector<T_BaseType>>
class TTN::BufferBase_t< T_BaseType, T_BufferType, T_VectorType >

Helper class which adds a range check to an array access if NDEBUG is not defined.

The helper class only provides read only access to the array, but allows a derived class to add write access if permitted by the base type.
