Method Summary

All Methods Instance Methods Abstract Methods Default Methods
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 java.util.List<S2Point>`	`vertices()`	Returns the vertices in this shape.

- Method Detail
  - 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 java.util.List<S2Point> vertices()
```
    Returns the vertices in this shape. Less efficient but may be more convenient.
