object BatchDispatcher

A BatchDispatcher is responsible for distributing messages (BatchMsg) within a batch.

A BatchDispatcher handles and distributes messages between currently active members of a batch. These messages are essentially JSON Patches after RFC 6902 and used to describe changes in the batch session data. The session data are stored and persisted with the Batch.

A BatchChannelActor is always opened during initialization of jatos.js (where a GroupChannelActor is opened only after the group was joined). A BatchChannelActor registers and unregisters itself in a BatchDispatcher.

A new BatchDispatcher is created by the BatchDispatcherRegistry. If a BatchDispatcher has no more members, it closes itself.
