Detailed Description

template<int K, typename DataT>
struct lsst::ap::cluster::detail::Point< K, DataT >

An entry in the data array to be indexed using a k-d tree. It contains point coordinates, along with the following additional pieces of information:

• An integer used to embed a singly linked list of range query results in the data array.
• A double used to store the distance of the point to the range query input point.
• The reachability-distance of the point (defined by the OPTICS algorithm).
• An object (or pointer) from which coordinates were obtained.

Note that if DataT is a pointer, then it is the responsibility of calling code to ensure that the lifetimes of the objects pointed to exceed the lifetimes of any Points referencing them.
