Property Details

<Boolean> defaultVisibility

Default visibility of the layers in the map service.
Known values: true | false

<Number> id

Layer ID assigned by ArcGIS Server for a layer. The topmost layer is 0, and each layer follows sequentially. If a layer is added or removed from the source map document, the ID values will shift accordingly.

<Number> maxScale

The maximum visible scale for each layer in the map service. If the map is zoomed in beyond this scale the layer will not be visible. A value of 0 means that the layer does not have a maximum scale. This property is only available for map services published using ArcGIS Server 10 SP1 or later. (Added at v2.1)

<Number> minScale

The minimum visible scale for each layer in the map service. If the map is zoomed out beyond this scale the layer will not be visible. A value of 0 means that the layer does not have a minimum scale. This property is only available for map services published using ArcGIS Server 10 SP1 or later. (Added at v2.1)

<String> name

Layer name as defined in the map service.

<Number> parentLayerId

If the layer is part of a group layer, it will include the parent ID of the group layer. Otherwise, the value is -1. If a layer is added or removed from the source map document, the ID values will shift accordingly.

<Number[]> subLayerIds

If the layer is a parent layer, it will have one or more sub layers included in an array. Otherwise, the value is null. If a layer is added or removed from the source map document, the ID values will shift accordingly.
