Class MUCRoom

    • Field Detail

      • occupants

        public final ArrayList<MUCRole> occupants
        All occupants that are associated with this room.

      • isDestroyed

        public boolean isDestroyed
        After a room has been destroyed it may remain in memory, but it won't be possible to use it. When a room is destroyed it is immediately removed from the MultiUserChatService, but it's possible that while the room was being destroyed it was being used by another thread, so we need to protect the room under these rare circumstances.

      • send

        public void send​(@Nonnull
                 org.xmpp.packet.Packet packet,
                 @Nonnull
                 MUCRole sender)
        Sends a packet to the occupants of the room. The second argument defines the sender/originator of the stanza. Typically, this is the same entity that's also the 'subject' of the stanza (eg: someone that changed its presence or nickname). It is important to realize that this needs to be the case. When, for example, an occupant is made a moderator, the 'sender' typically is the entity that granted the role to another entity. It is also possible for the sender to be a reflection of the room itself. This scenario typically occurs when the sender can't be identified as an occupant of the room, such as, for example, changes applied through the Openfire admin console.
        Parameters:
        packet - The packet to send
        sender - Representation of the entity that sent the stanza.

        Broadcasts the presence stanza as captured by the argument to all occupants that are local to the local domain (in other words, it excludes occupants that are connected via FMUC).
        Parameters:
        presence - The presence stanza
        isJoinPresence - If the presence is sent in the context of joining the room.

      • broadcast

        public void broadcast​(@Nonnull
