	Summary	Defined By
fault	The fault event is dispatched when a service call fails and isn't handled by the Operation itself.	AbstractService
invoke	The invoke event is dispatched when a service Operation is invoked so long as an Error is not thrown before the Channel attempts to send the message.	AbstractService
result	The result event is dispatched when a service call successfully returns and isn't handled by the Operation itself.	AbstractService

Property Detail

concurrency

property

concurrency:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Value that indicates how to handle multiple calls to the same service. 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.
single - 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.
last - 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.

Implementation
public function get concurrency():String
public function set concurrency(value:String):void

convertParametersHandler

property

public var convertParametersHandler:Function

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

An optional function, primarily intended for framework developers who need to install a function to get called with the parameters passed to each remote object invocation. The function takes an array of parameters and returns the potentially altered array. The function definition should look like: function myParametersFunction(parameters:Array):Array

convertResultHandler

property

public var convertResultHandler:Function

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

An optional function, primarily intended for framework developers who need to install a hook to process the results of an operation before notifying the result handlers. The function definition should look like: function myConvertResultsFunction(result: operation:AbstractOperation): It is passed the result just after the makeObjectsBindable conversion has been done but before the result event is created.

endpoint

property

endpoint:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

This property allows the developer to quickly specify an endpoint for a RemoteObject destination without referring to a services configuration file at compile time or programmatically creating a ChannelSet. It also overrides an existing ChannelSet if one has been set for the RemoteObject service.

If the endpoint url starts with "https" a SecureAMFChannel will be used, otherwise an AMFChannel will be used. Two special tokens, {server.name} and {server.port}, can be used in the endpoint url to specify that the channel should use the server name and port that was used to load the SWF.

Note: This property is required when creating AIR applications.

Implementation
public function get endpoint():String
public function set endpoint(value:String):void

makeObjectsBindable

property

makeObjectsBindable:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

When this value is true, anonymous objects returned are forced to bindable objects.

Implementation
public function get makeObjectsBindable():Boolean
public function set makeObjectsBindable(value:Boolean):void

showBusyCursor

property

showBusyCursor:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

If true, a busy cursor is displayed while a service is executing. The default value is false.

Implementation
public function get showBusyCursor():Boolean
public function set showBusyCursor(value:Boolean):void

source

property

source:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Lets you specify a source value on the client; not supported for destinations that use the JavaAdapter. This allows you to provide more than one source that can be accessed from a single destination on the server.

Implementation
public function get source():String
public function set source(value:String):void

Constructor Detail

RemoteObject

()

Constructor

public function RemoteObject(destination:String = null)

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Creates a new RemoteObject.

Parameters

destination:String (default = null) — [optional] Destination of the RemoteObject; should match a destination name in the services-config.xml file.

Method Detail

getOperation

()

method

override public function getOperation(name:String):AbstractOperation

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Returns an Operation of the given name. If the Operation wasn't created beforehand, a new mx.rpc.remoting.Operation is created during this call. Operations are usually accessible by simply naming them after the service variable (myService.someOperation), but if your Operation name happens to match a defined method on the service (like setCredentials), you can use this method to get the Operation instead.

Parameters

name:String — Name of the Operation.

Returns

AbstractOperation — Operation that executes for this name.

setRemoteCredentials

()

method

override public function setRemoteCredentials(remoteUsername:String, remotePassword:String, charset:String = null):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

If a remote object is managed by an external service, such a ColdFusion Component (CFC), a username and password can be set for the authentication mechanism of that remote service.

Parameters

	`remoteUsername:String` — the username to pass to the remote endpoint

	`remotePassword:String` — the password to pass to the remote endpoint

	`charset:String` (default = `null`) — The character set encoding to use while encoding the remote credentials. The default is null, which implies the legacy charset of ISO-Latin-1. The only other supported charset is "UTF-8".

toString

()

method

public function toString():String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Represents an instance of RemoteObject as a String, describing important properties such as the destination id and the set of channels assigned.

Returns

String — Returns a String representing an instance of a RemoteObject.
