Methods
ProGeoJSONLayer.Load() Method
Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance. This method must be called by the developer when accessing a resource that will not be loaded in a View. The load() method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.
public override System.Threading.Tasks.Task Load();
Returns
ProGeoJSONLayer.Load(IJSRuntime, JsModuleManager, CancellationToken) Method
Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance. This method must be called by the developer when accessing a resource that will not be loaded in a View. The load() method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.
public override System.Threading.Tasks.Task Load(Microsoft.JSInterop.IJSRuntime jsRuntime, dymaptic.GeoBlazor.Core.JsModuleManager jsModuleManager, System.Threading.CancellationToken cancellationToken);
Parameters
jsRuntime Microsoft.JSInterop.IJSRuntime
The dependency-injected Blazor IJSRuntime instance to connect to JavaScript.
jsModuleManager dymaptic.GeoBlazor.Core.JsModuleManager
The dependency-injected GeoBlazor JsModuleManager instance to load JavaScript modules.
cancellationToken System.Threading.CancellationToken
A cancellation token to cancel the operation.
Returns
ProGeoJSONLayer.Load(CancellationToken) Method
Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance. This method must be called by the developer when accessing a resource that will not be loaded in a View. The load() method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.
public override System.Threading.Tasks.Task Load(System.Threading.CancellationToken cancellationToken);
Parameters
cancellationToken System.Threading.CancellationToken
Returns
Remarks
It’s possible to provide a signal to stop being interested into a Loadable instance load status. When the signal is aborted, the instance does not stop its loading process, only cancelLoad can abort it.
ProGeoJSONLayer.ParseJSON() Method
Method for pre-parsing the GeoJSON content from the Url or SourceJSON properties before sending to ArcGIS. This is called automatically when the ProGeoJSONLayer is added in markup or when layer.Load() is called. If the layer is added to the map in code, this method or load should be called first.
public System.Threading.Tasks.Task ParseJSON();
