GetLayers()

Summary

Gets information on layers in the system and the current layer.

 

Changes

In Version 2018 added the optional array of types.

 

Syntax

layer_array = GetLayers(opt array types)

 

Argument	Contents
types	An optional array of strings with one or more layer types

 

Returns

An array of three elements:

 

Element	Type	Contents
1	Array	An array of the names of layers in the system (strings)
2	Integer	The index of the current layer in the list of names
3	String	The name of the current layer

 

Notes

• The array of types is an optional argument.

• The array of types, if provided, restricts the layer types. For a description of the types, see IsLayer.

• If no layers are present, the return value is null. If there is no current layer, the second array element is -1 and the third is null.

Example

lyr_info = GetLayers()

if lyr_info[3] = null then SetLayer(lyr_info[1][1])

 

lyrs = GetLayers({"Point"})

ShowArray(lyrs[1])
