109 |

110 |

111 Instead of completing the notification request with KErrNotSupported the it is passed to |
|
112 CStateAdaptationRefEventHandler which is an active object wiht lower priority compared to |
|
113 the server active object.Because of this a delay will be introduced in completing the notification |
|
114 request so that other active objects can run avoiding infinite loop and starvation of other |
|
115 active objects,which will be the case if the notification request is immediately completed. |
|
116 This is strictly for testing purposes.On a device this call will be replaced by a notification request |
|
117 to cooperative system. |
