Properties
Geometry.Cache Property
The cache is used to store values computed from geometries that need to be cleared or recomputed upon mutation.
ArcGIS Maps SDK for JavaScript
public string? Cache { get; set; }
Property Value
Geometry.Extent Property
The Extent of the geometry.
public dymaptic.GeoBlazor.Core.Components.Geometries.Extent? Extent { get; set; }
Property Value
Geometry.HasM Property
Indicates if the geometry has M values.
ArcGIS Maps SDK for JavaScript
public System.Nullable<bool> HasM { get; set; }
Property Value
System.Nullable<System.Boolean>
Geometry.HasZ Property
Indicates if the geometry has z-values (elevation).
ArcGIS Maps SDK for JavaScript
public System.Nullable<bool> HasZ { get; set; }
Property Value
System.Nullable<System.Boolean>
Geometry.SpatialReference Property
The spatial reference of the geometry.
default WGS84 (wkid: 4326)

Property Value
Methods
Geometry.GetCache() Method
Asynchronously retrieve the current value of the Cache property.
public System.Threading.Tasks.Task<string?> GetCache();
Returns
System.Threading.Tasks.Task<System.String>
Geometry.GetExtent() Method
Asynchronously retrieve the current value of the SpatialReference property.
public System.Threading.Tasks.Task<dymaptic.GeoBlazor.Core.Components.Geometries.Extent?> GetExtent();
Returns
System.Threading.Tasks.Task<Extent>
Geometry.GetHasM() Method
Asynchronously retrieve the current value of the HasM property.
public System.Threading.Tasks.Task<System.Nullable<bool>> GetHasM();
Returns
System.Threading.Tasks.Task<System.Nullable<System.Boolean>>
Geometry.GetHasZ() Method
Asynchronously retrieve the current value of the HasZ property.
public System.Threading.Tasks.Task<System.Nullable<bool>> GetHasZ();
Returns
System.Threading.Tasks.Task<System.Nullable<System.Boolean>>
Geometry.RegisterChildComponent(MapComponent) Method
Called from dymaptic.GeoBlazor.Core.Components.MapComponent.OnInitializedAsync to “Register” the current component with its 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.
Remarks
This method is an implementation detail and should not be called directly by consumers. In future versions, this may be changed to an internal method. If you see no other way to register a child component, please open an issue on GitHub.
Geometry.SetHasM(Nullable) Method
Asynchronously set the value of the HasM property after render.
public System.Threading.Tasks.Task SetHasM(System.Nullable<bool> value);
Parameters
value System.Nullable<System.Boolean>
The value to set.
Returns
Geometry.SetHasZ(Nullable) Method
Asynchronously set the value of the HasZ property after render.
public System.Threading.Tasks.Task SetHasZ(System.Nullable<bool> value);
Parameters
value System.Nullable<System.Boolean>
The value to set.
Returns
Geometry.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
Remarks
This method is an implementation detail and should not be called directly by consumers. In future versions, this may be changed to an internal method.
Geometry.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();
Implements 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
