This component helps you manage the results for asynchronous calls made from RPC based services, typically from MXML components. While each individual service and operation dispatches result and fault events, it is common to need to use the same operation in different parts of your application. Using one event listener or lastResult value across the entire application can be awkward. Rather than creating two service components which refer to the same service, you can use a simple lightweight CallResponder to manage the event listeners and lastResult value for a specific invocation of a service.

You set the token property of this component to the AsyncToken returned by the service. You can then add event listeners on this component instead of having to add them to each AsyncToken returned. This component also maintains the lastResult property which is a copy of the value returned by the last successful result event dispatched by a token monitored by this service. Though you can bind to either the callResponder.token.result or callResponder.lastResult, the latter will be preserved while a second call to the same service is in progress while the former will be reset as soon as a new service invocation is started.

Egenskapsdetaljer

lastResult

egenskap

lastResult:*

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

Flash Player 9, AIR 1.1

This property stores the result property of the token each time it delivers a successful result. You can bind to or access this property instead of the token.result property to keep your code from seeing that value cleared out on the second and subsequent call to a particular service method. Additionally, if a fault occurs this value will still be set to the last successful result returned by a token monitored by this CallResponder.

Den här egenskapen kan användas som källan för databindning. När den här egenskapen ändras, skickas händelsen propertyChange .

Implementering
public function get lastResult():*
public function set lastResult(value:any):void

token

egenskap

token:mx.rpc:AsyncToken

Språkversion:

ActionScript 3.0

Produktversion:

Körningsmiljöversioner:

Flash Player 9, AIR 1.1

Each CallResponder dispatches result and fault events received from a single token. This property value specifies that token. You typically set this property to the AsyncToken object returned by the service.

Den här egenskapen kan användas som källan för databindning. När den här egenskapen ändras, skickas händelsen propertyChange .

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.

`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.
