Class
JimuLayerView is the wrapper class for ArcGIS Maps SDK for JavaScript Layer and LayerView .
It is created by a JimuMapView using a layer DataSource .
A layer view may have a related data source. If it has the data source, the feature selection will be synced to data source selection and will use the data source URL params. If it does not have the data source, the feature selection will use the feature_selection URL param.
Properties
| Property | Type | Notes |
|---|---|---|
boolean | true means the JimuLayerView is created from runtime. e.g. The JimuLayerView is created by AddData widget at runtime. false means the layer is a builtin layer of WebMap or WebScene. | |
string | The id of the JimuLayerView instance. It connects the JimuMapView.id and the JimuLayerId with "-" | |
number | The order defined in the webmap | |
string | The jimuMapViewId is the corresponding JimuMapView instance id. | |
any | The layer is the corresponding layer object in ArcGIS JavaScript API View.map. | |
string | The layerDataSourceId is the corresponding data source id. This id always has value, but the layer data source may not be created. | |
string | The layer type, see ArcGIS Maps SDK for JavaScript Layer type. | |
