Description saved by the formatter when an error occurs. For the possible values of this property, see the description of each formatter.
Subclasses must set this value
in the format() method.
resourceManager | property |
resourceManager:IResourceManager [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A reference to the object which manages all of the application's localized resources. This is a singleton instance which implements the IResourceManager interface.
This property can be used as the source for data binding. When this property is modified, it dispatches the unused event.
Implementation

format | () | method |
public function format(value:Object):String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Formats a value and returns a String containing the new, formatted, value. All subclasses must override this method to implement the formatter.
Parameters
value:Object — Value to be formatted.
|
String — The formatted string.
|
resourcesChanged | () | method |
protected function resourcesChanged():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
This method is called when a Formatter is constructed,
and again whenever the ResourceManager dispatches
a "change" Event to indicate
that the localized resources have changed in some way.
This event will be dispatched when you set the ResourceManager's
localeChain property, when a resource module
has finished loading, and when you call the ResourceManager's
update() method.
Subclasses should override this method and, after calling
super.resourcesChanged(), do whatever is appropriate
in response to having new resource values.
