Interface MultiUserChatService

    All Known Implementing Classes:
    MultiUserChatServiceImpl
    public interface MultiUserChatService
extends org.xmpp.component.Component
    Manages groupchat conversations, chatrooms, and users. This class is designed to operate independently from the rest of the Jive server infrastruture. This theoretically allows deployment of the groupchat on a separate server from the main IM server.

        room - the room that received the message.
        message - the message to log as part of the conversation in the room.
