| 19 | \internal |
| 20 | \brief This class is responsible for the AT-SPI cache interface. |
| 21 | |
| 22 | The idea behind the cache is that starting an application would |
| 23 | result in many dbus calls. The way GTK/Gail/ATK work is that |
| 24 | they create accessibles for all objects on startup. |
| 25 | In order to avoid querying all the objects individually via DBus |
| 26 | they get sent by using the GetItems call of the cache. |
| 27 | |
| 28 | Additionally the AddAccessible and RemoveAccessible signals |
| 29 | are responsible for adding/removing objects from the cache. |
| 30 | |
| 31 | Currently the Qt bridge chooses to ignore these. |
