    A GroupDispatcher is an Akka Actor responsible for distributing messages (GroupMsg) within a group.

    A GroupDispatcher is an Akka Actor responsible for distributing messages (GroupMsg) within a group. Thus it is the central class handling a group.

    A GroupDispatcher only handles the GroupChannels but is not responsible for the actual joining of a GroupResult. This is done prior to creating a GroupDispatcher by the GroupAdministration which persists all data in a GroupResult. Who's member in a group is ultimately defined by the GroupResult.

    A GroupChannelActor is only opened after a StudyResult joined a GroupResult, which is done in the GroupAdministration. Group data (e.g. who's member) are persisted in a GroupResult entity. A GroupChannelActor is closed after the StudyResult left the group.

    A GroupChannelActor registers in a GroupDispatcher by sending the RegisterChannel message and unregisters by sending a UnregisterChannel message.

    A new GroupDispatcher is created by the GroupDispatcherRegistry. If a GroupDispatcher has no more members it closes itself.

    A GroupDispatcher handles all messages specified in the GroupDispatcherProtocol. There are fundamentally three different message types: 1) group session patches, 2) broadcast messages, and 3) direct messages for a particular group member.

    The group session patches are JSON Patches after RFC 6902 and used to describe changes in the group session data. The session data are stored in the GroupResult.

case class GroupMsg(json: JsObject, tellWhom: TellWhom = TellWhom.Unknown) extends Product with Serializable

Message format used for communication in the group channel between the GroupDispatcher and the group members. A GroupMsg contains a JSON node. If the JSON has a key named 'recipient' the message is intended for one particular group member - otherwise it's a broadcast message. If the JSON has a 'action' key it is an group action message.

The parameter 'tellWhom' can be used to address the recipient.
