  • Method Summary

    Modifier and Type
    Method
    Description
    int
    numVertices()
    Returns the number of vertices.
    S2Point
    vertex(int vertexId)
    Returns a vertex of this shape, from 0 (inclusive) to numVertices() (exclusive).
    default List<S2Point>
    vertices()
    Returns the vertices in this shape.

  • Method Details

    • numVertices

      int numVertices()
      Returns the number of vertices. May be different from S2Shape.numEdges().

    • vertex

      S2Point vertex(int vertexId)
      Returns a vertex of this shape, from 0 (inclusive) to numVertices() (exclusive).

    • vertices

      default List<S2Point> vertices()
      Returns the vertices in this shape. Less efficient but may be more convenient.
