Interfacepublic interface IModuleInfo extends flash.events.IEventDispatcher

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

An interface that acts as a handle for a particular module. From this interface, the module status can be queried, its inner factory can be obtained, and it can be loaded or unloaded.

    public function get data():Object
    public function set data(value:Object):void
errorproperty 
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

factoryproperty 
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:Boolean  [read-only]

Language Version : ActionScript 3.0
Product Version : Flex 3

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.

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 info() method.

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


Implementation
    public function get setup():Boolean
urlproperty 
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.

See also

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.
