Property Detail

arguments

property

public var arguments:Object

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The arguments to pass to the Operation when it is invoked. If you call the send() method with no parameters, an array based on this object is sent. If you call the send() method with parameters (or call the function directly on the service) those parameters are used instead of whatever is stored in this property. For RemoteObject Operations the associated argumentNames array determines the order of the arguments passed.

name

property

name:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The name of this Operation. This is how the Operation is accessed off the service. It can only be set once.

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

properties

property

public var properties:Object

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

This is a hook primarily for framework developers to register additional user specified properties for your operation.

service

property

service:AbstractService [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Provides convenient access to the service on which the Operation is being invoked. Note that the service cannot be changed after the Operation is constructed.

Implementation
public function get service():AbstractService

Constructor Detail

AbstractOperation

()

Constructor

public function AbstractOperation(service:AbstractService = null, name:String = null)

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Creates a new Operation. This is usually done directly by the MXML compiler or automatically by the service when an unknown Operation has been accessed. It is not recommended that a developer use this constructor directly.

Parameters

	`service:AbstractService` (default = `null`) — The service on which the Operation is being invoked.

	`name:String` (default = `null`) — The name of the new Operation.

Method Detail

send

()

method

public function send(... args):mx.rpc:AsyncToken

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Executes the method. Any arguments passed in are passed along as part of the method call. If there are no arguments passed, the arguments object is used as the source of parameters.

Parameters

... args — Optional arguments passed in as part of the method call. If there are no arguments passed, the arguments object is used as the source of parameters.

Returns

mx.rpc:AsyncToken — AsyncToken object. The same object is available in the result and fault events from the token property.

Event Detail

fault

Event

Event Object Type: mx.rpc.events.FaultEvent
property FaultEvent.type = mx.rpc.events.FaultEvent.FAULT

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Dispatched when an Operation call fails.

The FAULT event type.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	true, calling preventDefault() from the associated token's responder.fault method will prevent the service or operation from dispatching this event
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`fault`	The Fault object that contains the details of what caused this event.
`message`	The Message associated with this event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
`token`	The token that represents the call to the method. Used in the asynchronous completion token pattern.

result

Event

Event Object Type: mx.rpc.events.ResultEvent
property ResultEvent.type = mx.rpc.events.ResultEvent.RESULT

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Dispatched when an Operation invocation successfully returns.

The RESULT event type.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	true, preventDefault() from the associated token's responder.result method will prevent the service or operation from dispatching this event
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`message`	The Message associated with this event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
`result`	Result that the RPC call returns.
`token`	The token that represents the indiviudal call to the method. Used in the asynchronous completion token pattern.
