## Inherits from

CGAL::Segment_Delaunay_graph_Linf_2< Gt, DS >.

## Definition

This class is equivalent to the `Segment_Delaunay_graph_hierarchy_2` class, but it uses `Segment_Delaunay_graph_Linf_2<Gt,DS>` at every level of the hierarchy (instead of `Segment_Delaunay_graph_2<Gt,DS>` at each level of `Segment_Delaunay_graph_hierarchy_2`).

The `Segment_Delaunay_graph_Linf_hierarchy_2` class derives publicly from the `Segment_Delaunay_graph_Linf_2<Gt,DS>` class and has the same interface. For more details related to the template parameters, see the documentation of `Segment_Delaunay_graph_hierarchy_2`.

The class `Segment_Delaunay_graph_Linf_hierarchy_2` should be preferred when the size of the input is large and the input sites are inserted one by one (e.g., when the whole input is not known in advance): Experiments suggest that the hierarchy is faster than the plain segment Delaunay graph when the size of the input exceeds 1000 sites. If the whole input is known in advance, another option is to use the plain segment Delaunay graph but only after spatial sorting of the sites. See also the examples in the User Manual for different uses of the hierarchy and spatial sorting.
