Constant Detail

LAST

Constant
public static const LAST:String = "last"

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Making a request causes the client to ignore a result or fault for any current outstanding request. Only the result or fault for the most recent request will be dispatched on the client. This may simplify event handling in the client application, but care should be taken to only use this mode when results or faults for requests may be safely ignored.

MULTIPLE

Constant 
public static const MULTIPLE:String = "multiple"

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Existing requests are not cancelled, and the developer is responsible for ensuring the consistency of returned data by carefully managing the event stream.

SINGLE

Constant 
public static const SINGLE:String = "single"

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Making only one request at a time is allowed on the method; additional requests made while a request is outstanding are immediately faulted on the client and are not sent to the server.
