com.google.common.geometry.S2Predicates.VoronoiSiteExclusion

Enclosing class:

S2Predicates

static class S2Predicates.VoronoiSiteExclusion
extends java.lang.Object

A test for which (if any) of two Voronoi sites within R of an edge PQ are covered by the other.

Does not offer generally correct results for all inputs, so that multiple strategies may be implemented for different classes of input.
