Use the <mx:RemoteObject> tag to represent an HTTPService object in an MXML file. This tag gives you access to the methods of Java objects using Action Message Format (AMF) encoding.

The <mx:RemoteObject> tag accepts the following tag attributes:

 <mx:RemoteObject
  Properties
  concurrency="multiple|single|last"
  destination="No default."
  id="No default."
  endpoint="No default."
  showBusyCursor="false|true"
  source="No default." (currently, Adobe ColdFusion only)
  makeObjectsBindable="false|true"
  
  Events
  fault="No default."
  result="No default."  
 />

<mx:RemoteObject> can have multiple <mx:method> tags, which have the following tag attributes:

 <mx:method
  Properties
  concurrency="multiple|single|last"
  name="No default, required."
  makeObjectsBindable="false|true"
         
 Events
  fault="No default."
  result="No default."
 />

It then can have a single <mx:arguments> child tag which is an array of objects that is passed in order.

	Özellik		Tanımlayan:
		channelSet : ChannelSet Provides access to the ChannelSet used by the service.	AbstractService
		concurrency : String Value that indicates how to handle multiple calls to the same service.	RemoteObject
		convertParametersHandler : Function 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.	RemoteObject
		convertResultHandler : Function 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.	RemoteObject
		destination : String The destination of the service.	AbstractService
		endpoint : String 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.	RemoteObject
		makeObjectsBindable : Boolean When this value is true, anonymous objects returned are forced to bindable objects.	RemoteObject
		managers : Array The managers property stores a list of data managers which modify the behavior of this service.	AbstractService
		operations : Object The Operations array is usually only set by the MXML compiler if you create a service using an MXML tag.	AbstractService
		requestTimeout : int Provides access to the request timeout in seconds for sent messages.	AbstractService
		showBusyCursor : Boolean If true, a busy cursor is displayed while a service is executing.	RemoteObject
		source : String Lets you specify a source value on the client; not supported for destinations that use the JavaAdapter.	RemoteObject

		initialize():void Called to initialize the service.	AbstractService
		initialized(document:Object, id:String):void Called automatically by the MXML compiler if the RemoteObject is set up using a tag.	RemoteObject
		logout():void Logs the user out of the destination.	AbstractService
		setCredentials(username:String, password:String, charset:String = null):void Sets the credentials for the destination accessed by the service when using Data Services on the server side.	AbstractService
		setRemoteCredentials(remoteUsername:String, remotePassword:String, charset:String = null):void [geçersiz kıl] 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.	RemoteObject
		toString():String Represents an instance of RemoteObject as a String, describing important properties such as the destination id and the set of channels assigned.	RemoteObject

	Özet	Tanımlayan:
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

Returns an Operation of the given name. If the Operation wasn't created beforehand, a new mx.rpc.remoting.mxml.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.

Parametreler

name:String — Name of the Operation.

Döndürür

AbstractOperation — Operation that executes for this name.

Called automatically by the MXML compiler if the RemoteObject is set up using a tag. If you create the RemoteObject through ActionScript you may want to call this method yourself as it is useful for validating any arguments.

Parametreler

	`document:Object` — the MXML document on which this RemoteObject lives

	`id:String` — the id of this RemoteObject within the document
