public function saveState():Object| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Saves the state of this object. The object contains name:value pairs for each property to be saved with the state.
The History Manager collects the state information from all components and encodes the information in a URL format. Most browsers have a length limitation on URLs, so the state information returned should be as minimal as possible.
ReturnerarObject — The state of this object.
