Map Class
The Map class contains properties and methods for storing, managing, and overlaying layers common to both 2D and 3D viewing. Layers can be added and removed from the map, but are rendered via a MapView (for viewing data in 2D) or a SceneView (for viewing data in 3D). Thus a map instance is a simple container that holds the layers, while the View is the means of displaying and interacting with a map’s layers and basemap.

Methods
Map.RegisterChildComponent(MapComponent) Method
Called from dymaptic.GeoBlazor.Core.Components.MapComponent.OnAfterRenderAsync(System.Boolean) to “Register” the current component with it’s parent.
public override System.Threading.Tasks.Task RegisterChildComponent(dymaptic.GeoBlazor.Core.Components.MapComponent child);

child MapComponent
The calling, child component to register
Returns
Exceptions
InvalidChildElementException
Throws if the current child is not a valid sub-component to the parent.
Map.UnregisterChildComponent(MapComponent) Method
Undoes the “Registration” of a child with its parent.
public override System.Threading.Tasks.Task UnregisterChildComponent(dymaptic.GeoBlazor.Core.Components.MapComponent child);
Parameters
child MapComponent
The child to unregister
Returns
Map.UpdateComponent() Method
Checks if the map is already rendered, and if so, performs forced updates as defined by the component type.
public override System.Threading.Tasks.Task UpdateComponent();
