Parameters:

aMessage

incoming message.

This method is called when the status of the connection to the service changes.

Parameters:

aStatus

is connection state indicator, which could be specified by the actual service invocation framework implementation. The following status codes are possible for any installed framework: KSenConnectionStatusNew Connection is being initialized, but not yet ready. KSenConnectionStatusReady Connection is ready to be used. For example, SubmitL() and SendL() methods (depending of framework) are in invocable state. KSenConnectionStatusExpired Connection is expired. Typically, a new connection needs next to be initialized in order to communicate with the underlying service behind this service connection.
