Property Detail

_keepLastResult | property

`protected var _keepLastResult:Boolean = true`

channelSet | property |

`channelSet:ChannelSet`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Provides access to the ChannelSet used by the service. The ChannelSet can be manually constructed and assigned, or it will be dynamically created to use the configured Channels for the `destination` for this service.

Implementation
`public function get channelSet():ChannelSet`
`public function set channelSet(value:ChannelSet):void`

destination | property |

`destination:String`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The destination of the service. This value should match a destination entry in the services-config.xml file.

Implementation
`public function get destination():String`
`public function set destination(value:String):void`

keepLastResult | property |

`keepLastResult:Boolean`

Product Version : | Flex 4.11

Runtime Versions : | Flash Player 10, AIR 3

Flag indicating whether the service's operations should keep their last call result for later access.

Setting this flag at the service level will set `keepLastResult` for each operation, unless explicitly set in the operation.

If set to true or not set, each operation's last call result will be accessible through its `lastResult` bindable property.

If set to false, each operation's last call result will be cleared after the call, and must be processed in the operation's result handler. This will allow the result object to be garbage collected, which is especially useful if the operation is only called a few times and returns a large result.

The default value is `true`.

Implementation
`public function get keepLastResult():Boolean`
`public function set keepLastResult(value:Boolean):void`

mx.rpc.AbstractInvoker.keepLastResult

managers | property |

`managers:Array`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The managers property stores a list of data managers which modify the behavior of this service. You can use this hook to define one or more manager components associated with this service. When this property is set, if the managers have a property called "service" that property is set to the value of this service. When this service is initialized, we also call the initialize method on any manager components.

Implementation
`public function get managers():Array`
`public function set managers(value:Array):void`

operations | property |

`operations:Object`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The Operations array is usually only set by the MXML compiler if you create a service using an MXML tag.

Implementation
`public function get operations():Object`
`public function set operations(value:Object):void`

requestTimeout | property |

`requestTimeout:int`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Provides access to the request timeout in seconds for sent messages. A value less than or equal to zero prevents request timeout.

Implementation
`public function get requestTimeout():int`
`public function set requestTimeout(value:int):void`
Constructor Detail

AbstractService | () | Constructor

`public function AbstractService(destination:String = null)`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Constructor.

Parameters

| `destination:String` (default = `null`)`` — The destination of the service.

Method Detail

disconnect | () | method

`public function disconnect():void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Disconnects the service's network connection and removes any pending request responders. This method does not wait for outstanding network operations to complete.

getOperation | () | method |

`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, subclasses are responsible for creating it 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.

initialize | () | method |

`public function initialize():void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Called to initialize the service.

logout | () | method |

`public function logout():void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Logs the user out of the destination. Logging out of a destination applies to everything connected using the same ChannelSet as specified in the server configuration. For example, if you're connected over the my-rtmp channel and you log out using one of your RPC components, anything that was connected over the same ChannelSet is logged out.

Note: Adobe recommends that you use the mx.messaging.ChannelSet.logout() method rather than this method.

See also

mx.messaging.ChannelSet.logout()

setCredentials | () | method |

`public function setCredentials(username:String, password:String, charset:String = null):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Sets the credentials for the destination accessed by the service when using Data Services on the server side. The credentials are applied to all services connected over the same ChannelSet. Note that services that use a proxy or a third-party adapter to a remote endpoint will need to setRemoteCredentials instead.

Parameters

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

setRemoteCredentials | () | method |

`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

The username and password to be used to authenticate a user when accessing a remote, third-party endpoint such as a web service through a proxy or a remote object through a custom adapter when using Data Services on the server side.

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".

Event Detail

fault | Event

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

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The fault event is dispatched when a service call fails and isn't handled by the Operation itself.

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.

invoke | Event |

Event Object Type: `mx.rpc.events.InvokeEvent`
InvokeEvent.type property = `mx.rpc.events.InvokeEvent.INVOKE`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

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.

The INVOKE event type.

The properties of the event object have the following values:

Property | Value
--- | ---
`bubbles` | false
`token` | The token that represents the indiviudal call to the method. Used in the asynchronous completion token pattern.
`cancelable` | true
`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 request 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 | Event |

ResultEvent.type property = `mx.rpc.events.ResultEvent.RESULT`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The result event is dispatched when a service call successfully returns and isn't handled by the Operation itself.

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.
