vertex.getHalfEdge()
None.
Method; gets a HalfEdge object that shares this vertex.
The following example shows how to get other half edges that share the same vertex:
var shape = fl.getDocumentDOM().selection[0];
var hEdge = shape.edges[0].getHalfEdge(0);
var theVertex = hEdge.getVertex();
var someHEdge = theVertex.getHalfEdge(); // Not necessarily the same half edge
var theSameVertex = someHEdge.getVertex();
fl.trace('the same vertex: ' + theSameVertex);
