Detailed Description

template<typename... Args>
struct boost::geometry::index::detail::equal_to< std::tuple< Args...>, false >

The function object comparing Values.

This specialization compares values of type std::tuple<Args...>. It's defined if the compiler supports tuples and variadic templates. It compares all members of the tuple from the first one to the last one.
