Property Detail

wsdl

property

wsdl:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The location of the WSDL document for this WebService. If you use a relative URL, make sure that the rootURL has been specified or that you created the WebService in MXML.

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

Constructor Detail

WebService

()

Constructor

public function WebService(destination:String = null, rootURL:String = null)

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Creates a new WebService. The destination, if specified, should match an entry in services-config.xml. If unspecified, the WebService uses the DefaultHTTP destination. The rootURL is required if you intend to use a relative URL to find the WSDL document for this WebService.

Parameters

	`destination:String` (default = `null`) — The destination of the WebService, should match a destination name in the services-config.xml file.

	`rootURL:String` (default = `null`) — The root URL of the WebService.

Method Detail

canLoadWSDL

()

method

public function canLoadWSDL():Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Returns a Boolean value that indicates whether the WebService is ready to load a WSDL (does it have a valid destination or wsdl specified).

Returns

Boolean — Returns true if the WebService is ready to load a WSDL; otherwise, returns false.

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.soap.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.

initializeOperation

()

method

protected function initializeOperation(operation:Operation):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Initializes a new Operation.

Parameters

operation:Operation — The Operation to initialize.

loadWSDL

()

method

public function loadWSDL(uri:String = null):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Instructs the WebService to download the WSDL document. The WebService calls this method automatically WebService when specified in the WebService MXML tag, but it must be called manually if you create the WebService object in ActionScript after you have specified the destination or wsdl property value.

Parameters

uri:String (default = null) — If the wsdl hasn't been specified previously, it may be specified here.

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 WebService as a String, describing important properties such as the destination id and the set of channels assigned.

Returns

String — Returns a String representation of the WebService.

Event Detail

load

property LoadEvent.type = mx.rpc.soap.LoadEvent.LOAD

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The LoadEvent.LOAD is dispatched when the WSDL document has loaded successfully.

The LOAD constant defines the value of the type property of the event object for a load event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	true
`wsdl`	WSDL object.
`location`	URI of the WSDL document
