Detailed Description

A chat room is the place where ChatMessage are exchanged.

To create (or find) a ChatRoom, you first need a ChatRoomParams object. A chat room is uniquely identified by it's local and remote SIP addresses, meaning you can only have one chat room between two accounts (unless the backend is Backend::FlexisipChat). Then you can call Core::searchChatRoom() or Core::createChatRoom(). Be careful as a Backend::FlexisipChat backend ChatRoom will be created asynchronously, so make sure you add a ChatRoomListener to the returned object to be notified when it will be in state State::Created. All chat rooms are loaded from database when the Core starts, and you can get them using Core::getChatRooms(). This method doesn't return empty chat rooms nor ones for which the local address doesn't match an existing Account identity, unless you specify otherwise in the [misc] section of your configuration file by setting hide_empty_chat_rooms=0 and/or hide_chat_rooms_from_removed_proxies=0.
