| Class | public final class DeleteFeaturesTask |
| Inheritance | DeleteFeaturesTask  BAServerTask BATask AbstractTask flash.events.EventDispatcher |
This task deletes features whose Object ID value is listed in the input oids array.
Typically, values of Object ID are enumerated in a repository feature layer from zero
(for shapefile workspace type) or one (in other cases). When features are removed from a repository
feature layer, Object IDs of remaining features can be changed. For example, in the case of a shapefile
workspace, Object IDs of remaining features are renumbered.
The result of this task is true if at least one feature was successfully deleted.

public function get lastResult():Boolean| DeleteFeaturesTask | () | Constructor |
public function DeleteFeaturesTask(urlOrClient:Object = null)Creates a new instance of the DeleteFeaturesTask class.
A new task can be constructed in two ways: as a task sharing a BAServerClient type instance
with other tasks (the urlOrClient parameter has the BAServerClient type) or
as a standalone task encapsulating its own client.
The base URL to the Business Analyst Server HTTP Service looks as follows:
http://{host}:{port}/ArcGIS/baserver/REST/services/DefaultMap/BAServer
The {host} and {port} parameters in this URL should be substituted with
valid Business Analyst Server host name and port, respectively.
urlOrClient:Object (default = null) |

| createCommand | () | method |
public function createCommand(oids:Array, changedItem:FolderItem, commandName:String = null):BACommandCreates a new command encapsulating this task and the given parameters.
Parameters
oids:Array — Array of OIDs of features to be deleted. This array should contain items of the int type.
| |
changedItem:FolderItem — Folder item containing a feature layer to be modified.
| |
commandName:String (default = null) |
BACommand — A new command.

| createParameters | () | method |
public static function createParameters(oids:Array, changedItem:FolderItem):IBATaskParametersCreates parameters of this task in order to execute it with a generic or batch task.
Parameters
oids:Array — Array of OIDs of features to be deleted. This array should contain items of the int type.
| |
changedItem:FolderItem — Folder item containing a feature layer to be modified.
|

| execute | () | method |
public function execute(oids:Array, changedItem:FolderItem, responder:IResponder = null):AsyncTokenSends a request for executing a Delete Features task to the Business Analyst Server HTTP (REST) Service.
A response can be received in two ways—in an optional
responder object passed in parameters
of this method and/or in listeners of fault and taskCompleted
events registered for this task.
The responder is notified first when a response is received and parsed.
Its fault method receives a parameter of the FaultEvent type and its
result method receives a parameter of the BATaskCompletedEvent type
whose result property contains the result object.
After that the received event is dispatched to listeners of this task.
If a response is succesfully received and parsed, the result is assigned to the
lastResult property of this task.
Parameters
oids:Array — Array of OIDs of features to be deleted. This array should contain items of the int type.
| |
changedItem:FolderItem — Folder item containing a feature layer to be modified.
| |
responder:IResponder (default = null) |
AsyncToken — Asynch token associated with the response.

| name | Constant |
public static const name:String = DeleteFeaturesTask name.
// oids is an array of Object IDs of features to delete.
// changedItem is a repository layer whose features will be deleted.
deleteFeaturesTask.execute(oids, changedItem, new Responder(resultHandler, faultHandler));
