error

property

error:Boolean [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

A flag that is true if there was an error during module loading.

This flag is true when the ModuleManager dispatches the ModuleEvent.ERROR event.

Implementation

factory

property

factory:IFlexModuleFactory [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The IFlexModuleFactory implementation defined in the module. This will only be non-null after the ModuleEvent.SETUP event has been dispatched (or the IModuleInfo.setup() method returns true). At this point, the IFlexModuleFactory.info() method can be called. Once a ModuleEvent.READY event is dispatched (or the IModuleInfo.ready() method returns true), it is possible to call the IFlexModuleFactory.create() method.

Implementation
public function get factory():IFlexModuleFactory

loaded

loaded:Boolean [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

A flag that is true if the load() method has been called on this module.

Implementation
public function get loaded():Boolean

ready

property

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

A flag that is true if the module is sufficiently loaded to get a handle to its associated IFlexModuleFactory implementation and call its create() method.

This flag is true when the ModuleManager dispatches the ModuleEvent.READY event.

Implementation
public function get ready():Boolean

setup

property

setup:Boolean [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

This flag is true when the ModuleManager dispatches the ModuleEvent.SETUP event.

Implementation
public function get setup():Boolean

url

property

url:String [read-only]

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The URL associated with this module (for example, "MyImageModule.swf" or "http://somedomain.com/modules/MyImageModule.swf". The URL can be local or remote, but if it is remote, you must establish a trust between the module's domain and the application that loads it.

Implementation
public function get url():String

Method Detail

load

()

method

 public function load(applicationDomain:ApplicationDomain = null, securityDomain:SecurityDomain = null, bytes:ByteArray = null, moduleFactory:IFlexModuleFactory = null):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Requests that the module be loaded. If the module is already loaded, the call does nothing. Otherwise, the module begins loading and dispatches progress events as loading proceeds.

Parameters

	`applicationDomain:ApplicationDomain` (default = `null`) — The current application domain in which your code is executing.

	`securityDomain:SecurityDomain` (default = `null`) — The current security "sandbox".

	`bytes:ByteArray` (default = `null`) — A ByteArray object. The ByteArray is expected to contain the bytes of a SWF file that represents a compiled Module. The ByteArray object can be obtained by using the URLLoader class. If this parameter is specified the module will be loaded from the ByteArray. If this parameter is null the module will be loaded from the url specified in the url property.

	`moduleFactory:IFlexModuleFactory` (default = `null`) — The moduleFactory of the caller. One use of the moduleFactory is to determine the parent style manager of the loaded module.

publish

()

method

public function publish(factory:IFlexModuleFactory):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Publishes an interface to the ModuleManager. This allows late (or decoupled) subscriptions to factories with a String handle. Use a URL that starts with publish:// to reference factories that are published in this manner.

Parameters

factory:IFlexModuleFactory — The class that implements the module's IFlexModuleFactory interface.

release

()

method

public function release():void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Releases the current reference to the module. This does not unload the module unless there are no other open references to it and the ModuleManager is set up to have only a limited number of loaded modules.

mx.modules.ModuleManager

unload

()

method

public function unload():void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Unloads the module. Flash Player and AIR will not fully unload and garbage collect this module if there are any outstanding references to definitions inside the module.

Dispatched by the backing ModuleInfo if there was an error during module loading.

Dispatched when there is an error downloading the module. The ModuleEvent.ERROR constant defines the value of the type property of the event object for an error event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`bytesLoaded`	Empty
`bytesTotal`	Empty
`cancelable`	false
`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`.
