Detailed Description

template<class Value_tp>
class mysql::iterators::detail::Dereferenceable_wrapper< Value_tp >

Auxiliary object that holds a value internally, and operator-> returns a pointer to the value.

This is also called an "arrow proxy".

This is useful to implement the operator-> for iterator classes for which operator* returns by value, rather than by reference.
