Methods
SimpleMarkerSymbol.Equals(object) Method
Determines whether the specified object is equal to the current object.
public override bool Equals(object? obj);
Parameters
obj System.Object
The object to compare with the current object.
Returns
System.Boolean
true if the specified object is equal to the current object; otherwise, false.
SimpleMarkerSymbol.GetHashCode() Method
Serves as the default hash function.
public override int GetHashCode();
Returns
System.Int32
A hash code for the current object.
SimpleMarkerSymbol.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);
Parameters
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.
SimpleMarkerSymbol.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
SimpleMarkerSymbol.ValidateRequiredChildren() Method
When a MapView is prepared to render, this will check to make sure that all properties with the
RequiredPropertyAttribute are provided.
public override void ValidateRequiredChildren();
Exceptions
MissingRequiredChildElementException
The consumer needs to provide the missing child component
MissingRequiredOptionsChildElementException
The consumer needs to provide ONE of the options of child components
