| PointAccessor (const NanoGrid< Point > &grid)

| return true if this access was initialized correctly
__hostdev__ const NanoGrid< Point > & | grid () const
__hostdev__ uint64_t | gridPoints (const AttT *&begin, const AttT *&end) const
| Return the total number of point in the grid and set the iterators to the complete range of points.
__hostdev__ uint64_t | leafPoints (const Coord &ijk, const AttT *&begin, const AttT *&end) const
| Return the number of points in the leaf node containing the coordinate ijk. If this return value is larger than zero then the iterators begin and end will point to all the attributes contained within that leaf node.
__hostdev__ uint64_t | voxelPoints (const Coord &ijk, const AttT *&begin, const AttT *&end) const
| get iterators over attributes to points at a specific voxel location
__hostdev__ const RootT & | root () const

| Return a const point to the cached node of the specified type.
__hostdev__ const NodeTrait< TreeT, LEVEL >::type * | getNode () const
__hostdev__ void | clear ()
