Method Detail

hasMultipleVertices

public static <T extends Point2D> boolean hasMultipleVertices(java.util.List<T> points)

Tests if the given list of points contains multiple vertices. This function can be used to test presence of multiple vertices in polylines and polygons. First and last point are not compared.

hasMultipleVertices

public static <T extends Point2D> boolean hasMultipleVertices(java.util.List<T> points,
                                                              boolean closed)

Tests if the given list of points contains multiple vertices. This function can be used to test presence of multiple vertices in polylines and polygons. First and last point are compared if flag 'closed' is set to true.

countMultipleVertices

public static <T extends Point2D> int countMultipleVertices(java.util.List<T> points)

Counts the number of multiple vertices in this point list.

countMultipleVertices

public static <T extends Point2D> int countMultipleVertices(java.util.List<T> points,
                                                            boolean closed)

Counts the number of multiple vertices in this point list. If flag 'closed' is set to true, extremities are also compared.

filterMultipleVertices

public static <T extends Point2D> java.util.List<T> filterMultipleVertices(java.util.List<T> vertices)

filterMultipleVertices

public static <T extends Point2D> java.util.List<T> filterMultipleVertices(java.util.List<T> vertices,
                                                                           boolean closed)
