GetNodeLinks()

Summary

Gets the IDs of links that begin or end at a node.

 

Syntax

link_list = GetNodeLinks(integer node_id)

 

Argument	Contents
id	ID of a node

 

Returns

An array of link IDs.

 

Notes

• GetNodeLinks() works only when the current layer is a node (endpoint) layer in a map. The function does not work on a layer that has been added to the workspace only.

Example

// This macro gets a list of all lines in and out of a point

SetLayer("Intersection")

id = RH2ID(LocateNearestRecord(ClickCoord(), 0.25))

link_list = GetNodeLinks(id)

 

Error Codes

Error Type	Meaning
Error	The current layer is of the wrong type
NotFound	There is no node with this ID in the current layer
