Property Details
<Boolean
BooleanDefault visibility of the layers in the map service.
Known values:
true | false<Number
NumberLayer 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.
Sample:
dynamicLayerInfo.id = 0;
<Number
NumberThe 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.
Sample:
dynamicLayerInfo.maxScale = 1000000; dynamicLayerInfo.minScale = 0;
<Number
NumberThe 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.
Sample:
dynamicLayerInfo.maxScale = 1000000; dynamicLayerInfo.minScale = 0;
<String
StringLayer name as defined in the map service.
<Number
NumberIf 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.
<LayerSource
LayerSourceThe source for the dynamic layer can be either a LayerMapSource or LayerDataSource. Requires ArcGIS Server 10.1 service.
Sample:
var dataSource = new esri.layers.TableDataSource(); dataSource.workspaceId = "d203"; dataSource.dataSourceName = "sde.SDE.states"; var layerSource = new esri.layers.LayerDataSource(); layerSource.dataSource = dataSource; dynamicLayerInfo.source = layerSource;
<Number[]
Number[]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.
