    An interface for rules which determine whether node points which are in boundaries of {link Lineal} geometry components are in the boundary of the parent geometry collection.

    An interface for rules which determine whether node points which are in boundaries of {link Lineal} geometry components are in the boundary of the parent geometry collection. The SFS specifies a single kind of boundary node rule, the {link Mod2BoundaryNodeRule} rule. However, other kinds of Boundary Node Rules are appropriate in specific situations (for instance, linear network topology usually follows the {link EndPointBoundaryNodeRule}.) Some JTS operations (such as {link RelateOp}, {link BoundaryOp} and {link IsSimpleOp}) allow the BoundaryNodeRule to be specified, and respect the supplied rule when computing the results of the operation.

    An example use case for a non-SFS-standard Boundary Node Rule is that of checking that a set of {link LineString}s have valid linear network topology, when turn-arounds are represented as closed rings. In this situation, the entry road to the turn-around is only valid when it touches the turn-around ring at the single (common) endpoint. This is equivalent to requiring the set of LineStrings to be simple under the {link EndPointBoundaryNodeRule}. The SFS-standard {link Mod2BoundaryNodeRule} is not sufficient to perform this test, since it states that closed rings have no boundary points.

    This interface and its subclasses follow the Strategy design pattern.

MultiValentEndPointBoundaryNodeRule

class MultiValentEndPointBoundaryNodeRule extends BoundaryNodeRule

A {link BoundaryNodeRule} which determines that only endpoints with valency greater than 1 are on the boundary. This corresponds to the boundary of a {link MultiLineString} being all the "attached" endpoints, but not the "unattached" ones.
