Furthermore, looking at<br>> <br>> the source name is what the entry is called in the DataEngine. the idea is <br>> this:<br>> <br>> you have a DataEngine and your are connected to one of the pieces of <br>> information it provides. in the Hotplug engine (which announces events like <br>> when you plug in a USB stick, for instance) this might be a disk drive. <br>> <br>> then you want to interact with it. in the Hotplug engine case, maybe you want <br>> to request that the disk be mounted. at that point you ask for the service for <br>> that source, and you do so by asking the DataEngine to give you a service for <br>> the source by that name.<br>> <br>> a concept we don't have is a "default service" for a DataEngine: you always <br>> need to ask for the service for a given source.<br>> <br>> in the case of a service-without-a-source, as in the case of notifications, <br>> one can ask directly for a Service without going through a DataEngine.<br>> <br><br>That's great, thanks for the comprehensive elucidation.<br><br>> for notifications, that Service needs to be written still.<br>> <br>> -- <br>> Aaron J.
