| autoNormalize | property |
autoNormalize:Boolean| Since : | ArcGIS API for Flex 2.3 |
If true, normalizes the geometries across the central meridian.
The default value is true.
This property can be used as the source for data binding.

concurrency:String
Value that indicates how to handle multiple calls to the same task. The default
value is multiple. The following values are permitted:
multiple Existing requests are not cancelled and the developer is
responsible for ensuring the consistency of returned data by carefully
managing the event stream. This is the default value.single Only a single request at a time is allowed on the task;
multiple requests generate a fault.last Making a request cancels any existing request. The default value is multiple.
This property can be used as the source for data binding.

disableClientCaching:BooleanIf true, adds a timestamp parameter ("_ts") to the REST request to prevent the request from being loaded from the browser's cache.
The default value is false.

method:String| Since : | ArcGIS API for Flex 2.1 |
URL request method to use. Valid values are either URLRequestMethod.GET or URLRequestMethod.POST. BaseTask will always POST if the URL is longer than 2000 characters or includes a "token" parameter, but using this property you can force a "POST" even for all other cases.
The default value is URLRequestMethod.GET.

requestTimeout:intThe request timeout in seconds. A value less than or equal to zero prevents request timeout.
The default value is -1.

| sendURLVariables | () | method |
protected function sendURLVariables(urlSuffix:String, urlVariables:URLVariables, responder:IResponder, operation:Function):AsyncToken| Since : | ArcGIS API for Flex 2.1 |
Sends an HTTP request.
Parameters
urlSuffix:String — [optional] Appended to the URL, for example, "/query"
| |
urlVariables:URLVariables — [optional] The request variables to be sent as URL parameters.
| |
responder:IResponder — [optional] Added to the AsyncToken. If there is a HTTP fault or the service returns an error,
the responder's fault is called, a fault event is dispatched and the operation is not called.
| |
operation:Function — [required] The callback function that is passed the decoded result and the
AsyncToken, for example, function handleExecute(decodedObject:Object, asyncToken:AsyncToken):void
|
AsyncToken — The AsyncToken that can be returned to the caller so that they can add responders to it.
