EndPointBoundaryNodeRule class
A {@link BoundaryNodeRule} which specifies that any points which are endpoints of lineal components are in the boundary of the parent geometry. This corresponds to the "intuitive" topological definition of boundary. Under this rule {@link LinearRing}s have a non-empty boundary (the common endpoint of the underlying LineString).
This rule is useful when dealing with linear networks. For example, it can be used to check whether linear networks are correctly noded. The usual network topology constraint is that linear segments may touch only at endpoints. In the case of a segment touching a closed segment (ring) at one point, the Mod2 rule cannot distinguish between the permitted case of touching at the node point and the invalid case of touching at some other interior (non-node) point. The EndPoint rule does distinguish between these cases, so is more appropriate for use.
