# geom.edge.next.index

Syntax

ir = geom.edge.next.index(e,i)
Get local index ir of a point within the next edge attached to this point (note: the same point has local index i within the source edge e). This can be used to iterate through all edges connected to a node with the geom.edge.next.edge function.
Returns: ir - node index with 1 $$\le$$ ir $$\le$$ 2 e - edge pointer i - node index with 1 $$\le$$ i $$\le$$ 2

Usage Example

The following example illustrates how geom.edge.next.index can be used to iterate through all edges attached to a node, counting the number of edges.

    global test21 = geom.edge.node.pos(pnt,2)
global test22 = geom.edge.pos(pnt)
; Test node to edge loop
global test23 = 0
local node_pnt = geom.node.find(setpnt,1)
local edge_pnt = geom.node.start.edge(node_pnt)
local node_ind = geom.node.start.index(node_pnt)
io.out(edge_pnt)
io.out(node_ind)
loop while edge_pnt # null
test23 = test23 + 1
local next_pnt = geom.edge.next.edge(edge_pnt,node_ind)
node_ind = geom.edge.next.index(edge_pnt,node_ind)
edge_pnt = next_pnt
io.out(edge_pnt)
