The factory operation takes a MediaResourceBase as input and produces a MediaElement as output.
The MediaFactory maintains a list of MediaFactoryItem objects, each of which encapsulates all the information necessary to create a specific MediaElement. The MediaFactory relies on the canHandleResourceFunction method of each MediaFactoryItem to find a MediaFactoryItem object that can handle the specified MediaResourceBase.
The factory interface also exposes methods for querying for specific MediaFactoryItem objects, and for loading plugins (which hold MediaFactoryItem objects).

Constructor.

public function addItem(item:MediaFactoryItem):void| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | OSMF 1.0 |
| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Adds the specified MediaFactoryItem to the factory. After the MediaFactoryItem has been added, for any MediaResourceBase that this MediaFactoryItem can handle, the factory will be able to create the corresponding media element. If a MediaFactoryItem with the same ID already exists in this factory, the new MediaFactoryItem object replaces it.
Parámetros
item:MediaFactoryItem — The MediaFactoryItem to add.
|
Emite
ArgumentError — If the argument is null or if the argument
has a null ID field.

| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Returns a MediaElement that can be created based on the specified MediaResourceBase.
Returns null if the factory cannot
find a MediaFactoryItem object
capable of creating such a MediaElement in this factory.
Parámetros
resource:MediaResourceBase — The MediaResourceBase for which a corresponding
MediaElement should be created.
|
MediaElement — The MediaElement that was created or null if no such
MediaElement could be created from the resource.
|

| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Gets the MediaFactoryItem at the specified index.
Parámetros
index:int — The index in the list from which to retrieve the MediaFactoryItem.
|
MediaFactoryItem — The MediaFactoryItem at that index or null if there is none.
|
getItemById | () | método |
public function getItemById(id:String):MediaFactoryItem| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | OSMF 1.0 |
| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Returns the MediaFactoryItem with the specified ID or null if the
specified MediaFactoryItem does not exist in this factory.
Parámetros
id:String — ID of the MediaFactoryItem to retrieve.
|
MediaFactoryItem — The MediaFactoryItem with the specified ID or null if the specified
MediaFactoryItem does not exist in this factory.

loadPlugin | () | método |
public function loadPlugin(resource:MediaResourceBase):void| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | OSMF 1.0 |
| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Load a plugin identified by the specified resource. The MediaFactory will not reload the plugin if it has already been loaded. Upon successful loading, the MediaFactoryItems within the plugin's PluginInfo property will be added to this MediaFactory, and a MediaFactoryEvent.PLUGIN_LOAD event will be dispatched. OtherwiseIf the load fails, a MediaFactoryEvent.PLUGIN_LOAD_ERROR event will be dispatched.
Parámetros
resource:MediaResourceBase — MediaResourceBase representing the plugin. For remote (dynamic)
plugins, use an URLResource pointing to the remote SWF to load. For local
(static) plugins, use a PluginInfoResource.
|
Emite
ArgumentError — If resource is null or resource is neither an URLResource
nor a PluginInfoResource.
|
removeItem | () | método |
public function removeItem(item:MediaFactoryItem):void| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | OSMF 1.0 |
| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Removes the specified MediaFactoryItem from the factory. If no such MediaFactoryItem exists in this factory, does nothing.
Parámetros
item:MediaFactoryItem — The MediaFactoryItem to remove.
|
Emite
ArgumentError — If the argument is null or if the argument
has a null ID field.
|
resolveItems | () | método |
protected function resolveItems(resource:MediaResourceBase, items:Vector.<MediaFactoryItem>):MediaFactoryItem
Returns the most appropriate MediaFactoryItem for the specified resource
out of the MediaFactoryItems in the specified list.
This method is invoked when createMediaElement is invoked
with a resource that more than one MediaFactoryItem can handle. Subclasses
can override to select the most appropriate one.
The default behavior is to select the first item which is not "native" to
the framework, under the theory that plugins ought to take precedence over
core media types. It makes this decision based on the presence or absence
of an id value which starts with "org.osmf".
