Remarks
Geometry Services are a special type of service not based on any specific geographic resource such as a Map Package but instead provide access to sophisticated and frequently used geometric operations which can be perform on individually specified geometries. To access these operations, the LocalGeometryService should be used in conjunction with the use of a GeometryService Task which references the underlying LocalGeometryService via the UrlGeometryService.
Example
The following example demonstrates starting a LocalGeometryService by using the static method GetServiceAsync. Once the service has started the code creates a new GeometryService task instance, sets the Url property and registers event handlers for the BufferCompleted event and the task Failed event. The following example demonstrates using the task extension GeometryService.InitializeWithLocalServiceAsync:
| C# |  Copy Code |
|---|---|
LocalGeometryService.GetServiceAsync(localGeometryService =>
{
// Create a new GeometryService task instance.
GeometryService geometryTask;
geometryTask = new GeometryService();
// Set the Url property to the Url of the LocalGeometryService.
geometryTask.Url = localGeometryService.UrlGeometryService;
// Register event handlers for the BufferCompleted and Failed events.
geometryTask.BufferCompleted += GeometryService_BufferCompleted;
geometryTask.Failed += GeometryService_Failed;
}); | |
| VB.NET | Copy Code |
|---|---|
LocalGeometryService.GetServiceAsync(Function(localServiceDelegate) ' Create a new GeometryService task instance. Dim geometryTask As GeometryService geometryTask = New GeometryService() ' Set the Url property to the Url of the LocalGeometryService. geometryTask.Url = localServiceDelegate.UrlGeometryService ' Register event handlers for the BufferCompleted and Failed events. geometryTask.BufferCompleted += GeometryService_BufferCompleted geometryTask.Failed += GeometryService_Failed End Function) | |
| C# | Copy Code |
|---|---|
GeometryService geometryTask = new GeometryService(); geometryTask.InitializeWithLocalServiceAsync(delegateService => { if (string.IsNullOrEmpty(geometryTask.Url)) { // Check delegateService.Error property. return; } // Continue to use geometryTask... }); | |
| VB.NET | Copy Code |
|---|---|
Dim geometryTask As New GeometryService() geometryTask.InitializeWithLocalServiceAsync(Function(delegateService) If String.IsNullOrEmpty(geometryTask.Url) Then ' Check delegateService.Error property. Exit Function End If ' Continue to use geometryTask... End Function) | |
