Detailed Description

template<class C, class COLL = typename C::value_type, class V = typename COLL::value_type>
class FWItemDetSetAccessor< C, COLL, V >

Generic class for creating accessors for containers which are implemented as a container of containers. This for example includes DetSetVector hence the name. Both the outer and the inner containers must follow the Random Access Container model and in particular must have a size() method. The outer collection must be iterable, while the inner collections must have an array subscript operator.
