| 47 | \internal | - |
| 48 | \brief This class is responsible for the AT-SPI cache interface. | - |
| 49 | - | |
| 50 | The idea behind the cache is that starting an application would | - |
| 51 | result in many dbus calls. The way GTK/Gail/ATK work is that | - |
| 52 | they create accessibles for all objects on startup. | - |
| 53 | In order to avoid querying all the objects individually via DBus | - |
| 54 | they get sent by using the GetItems call of the cache. | - |
| 55 | - | |
| 56 | Additionally the AddAccessible and RemoveAccessible signals | - |
| 57 | are responsible for adding/removing objects from the cache. | - |
| 58 | - | |
| 59 | Currently the Qt bridge chooses to ignore these. | - |
