halfEdge summary

#### Availability

Flash MX 2004.

#### Description

The HalfEdge object is the directed side of the edge of a Shape object (../Shape_object/shape_summary.md). An edge has two half edges. You can transverse the contours of a shape by "walking around" these half edges. For example, starting from a half edge, you can trace all the half edges around a contour of a shape, and return to the original half edge.
Half edges are ordered. One half edge represents one side of the edge; the other half edge represents the other side.

#### Method summary

The following methods are available for the HalfEdge object:

| Method | Description |

| halfEdge.getNext() (../HalfEdge_object/halfEdg1.md) | Gets the next half edge on the current contour. |
| halfEdge.getOppositeHalfEdge() (../HalfEdge_object/halfEdg2.md) | Gets the HalfEdge object on the other side of the edge. |
| halfEdge.getPrev() (../HalfEdge_object/halfEdg3.md) | Gets the preceding HalfEdge object on the current contour. |
| halfEdge.getVertex() (../HalfEdge_object/halfEdg4.md) | Gets the Vertex object (../Vertex_object/vertex_summary.md) at the head of the HalfEdge object. |
