``` Obtain a MUC Light ------------------ ``` MultiUserChatLight multiUserChatLight = multiUserChatLightManager.getMultiUserChatLight(roomJid); ``` `roomJid` is a EntityBareJid Create a new room ----------------- ``` multiUserChatLight.create(roomName, occupants); ``` or ``` multiUserChatLight.create(roomName, subject, customConfigs, occupants); ``` *roomName* is a `String` *subject* is a `String` *customConfigs* is a `HashMap` *occupants* is a `List` Destroy a room --------------- ``` multiUserChatLight.destroy(); ``` Leave a room ------------- ``` multiUserChatLight.leave(); ``` Change room name ---------------- ``` multiUserChatLight.changeRoomName(roomName); ``` *roomName* is a `String` Change subject -------------- ``` multiUserChatLight.changeSubject(subject); ``` *subject* is a `String` Set room configurations ----------------------- ``` multiUserChatLight.setRoomConfigs(customConfigs); ``` or ``` multiUserChatLight.setRoomConfigs(roomName, customConfigs); ``` *customConfigs* is a `HashMap` (which means [property name, value]) *roomName* is a `String` Manage changes on room name, subject and other configurations ------------------------------------------------------------- ``` // check if the message is because of a configurations change if (message.hasExtension(MUCLightElements.ConfigurationsChangeExtension.ELEMENT, MUCLightElements.ConfigurationsChangeExtension.NAMESPACE)) { // Get the configurations extension MUCLightElements.ConfigurationsChangeExtension configurationsChangeExtension = MUCLightElements.ConfigurationsChangeExtension.from(message);

``` *mucLightService* is a `DomainBareJid` **Get MUC Light services domains** ``` List domains = multiUserChatLightManager.getLocalServices(); ``` Get occupied rooms ------------------ ``` List occupiedRooms = multiUserChatLightManager.getOccupiedRooms(mucLightService); ``` *mucLightService* is a `DomainBareJid` Start a private chat -------------------- ``` Chat chat = multiUserChatLight.createPrivateChat(occupant, listener); ``` *occupant* is a `EntityJid` *listener* is a `ChatMessageListener` Send message to a room ---------------------- **Create message for an specific MUC Light** ``` Message message = multiUserChatLight.createMessage(); ``` **Send a message to an specific MUC Light** ``` multiUserChatLight.sendMessage(message); ``` *message* is a `Message` Manage blocking list -------------------- **Get blocked list** ``` // Get users and rooms blocked List jids = multiUserChatLightManager.getUsersAndRoomsBlocked(mucLightService); // Get rooms blocked List jids = multiUserChatLightManager.getRoomsBlocked(mucLightService); // Get users blocked List jids = multiUserChatLightManager.getUsersBlocked(mucLightService); ``` *mucLightService* is a `DomainBareJid` **Block rooms** ``` // Block one room multiUserChatLightManager.blockRoom(mucLightService, roomJid); // Block several rooms multiUserChatLightManager.blockRooms(mucLightService, roomsJids); ``` *mucLightService* is a `DomainBareJid` *roomJid* is a `Jid` *roomsJids* is a `List` **Block users** ``` // Block one user multiUserChatLightManager.blockUser(mucLightService, userJid);
