Remarks

This class is used to create and setup a desired presence state for a local user (outgoing presence) or get presence states for other users (incoming presence). Presence information is divided into 2 parts: an automatic part and an application part.

The automatic part consists of so-called presence channels and their availability. A channel is a way to communicate to a user including communication address and availability of the channel. The channels include a phone channel, a video channel, an IM channel and a calendar channel. For instance, phone channel represents a phone number of a user and current PresenceState of the channel. If the state of the phone channel is available, the user is able to receive calls. If the state is "on a call", the user is unlikely to accept a new call. The automatic part of presence information is controlled by the library and used for incoming presence only.

The application part of presence information consists of manually published PresenceState, PresenceLocationMode and a note. These are used for both incoming and outgoing presence, and controlled by the application. Application PresenceState is a presence state that a user wants to set their client to. Application PresenceLocationMode is also controlled by the user specifying their current location. Application note is just a short string representing some user comment regarding their current status.

Although there are many aspects to presence information, there is also an overall presence state populated automatically. The overall state should be used to represent the state of the user.
