Property Documentation

markers : list<interactiveMarker>

All markers.

seqNum : uint64_t

Sequence number.

The client will use this to detect if it has missed a subsequent update. Every update message will have the same sequence number as an init message. Clients will likely want to unsubscribe from the init topic after a successful initialization to avoid receiving duplicate data.
