| Körningsmiljöversioner: | 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.
Parametrar
value:Object — Value to be formatted.
|
String — The formatted string.
|
resourcesChanged | () | metod |
protected function resourcesChanged():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
