GetLayerDBPos()

Summary

Gets the layer "position" within a geographic file.

Syntax

position = GetLayerDBPos(string layer_name)

Returns

An integer indicating the layer index number within the geographic file, starting from zero.

Notes

• Line layers are stored in geographic files that have two layers. The first layer represents intersection points, and the second layer represents line features.

• Some geographic files from earlier versions of Caliper Corporation GIS products also include multiple layers. GetLayerDBPos() provides backward compatibility with those versions of geographic files.

Example

if GetLayerType() = "Line" then do
idx = GetLayerDBPos()
if idx = 0 then ShowMessage("The current layer is the node layer.")
end
