Structure of a session: session { -- properties -- conn -- the tcp connection notopen -- true if stream has not been initiated, removed after receiving <stream:steam> type -- the connection type. Valid values include: -- "c2s_unauthed" - connection has not been authenticated yet -- "c2s" - from a local client to the server username -- the node part of the client's jid (not defined before auth) host -- the host part of the client's jid (not defined before stream initiation) resource -- the resource part of the client's full jid (not defined before resource binding) full_jid -- convenience for the above 3 as string in username@host/resource form (not defined before resource binding) priority -- the resource priority, default: 0 presence -- the last non-directed presence with no type attribute. initially nil. reset to nil on unavailable presence. interested -- true if the resource requested the roster. Interested resources recieve roster updates. Initially nil. roster -- the user's roster. Loaded as soon as the resource is bound (session becomes a connected resource). -- methods -- send(x) -- converts x to a string, and writes it to the connection close(x) -- Disconnect the user and clean up the session, best call sessionmanager.destroy_session() instead of this in most cases } if session.full_jid (also session.roster and session.resource) then this is a "connected resource" if session.presence then this is an "available resource" (all available resources are connected resources) if session.interested then this is an "interested resource" (all interested resources are connected resources)
