Awareness and controlledIDs

1

Hello,

Does anyone know the purpose of the “controlledIDs” in the awarenessChangeHandler? How is it used?

y-websocket/utils.js at 5db415ab9b584dc1cd9a362e70fb8e976f21d6cd · yjs/y-websocket · GitHub

const awarenessChangeHandler = ({ added, updated, removed }, conn) => {
      const changedClients = added.concat(updated, removed)
      if (conn !== null) {
        const connControlledIDs = /** @type {Set<number>} */ (this.conns.get(conn))
        if (connControlledIDs !== undefined) {
          added.forEach(clientID => { connControlledIDs.add(clientID) })
          removed.forEach(clientID => { connControlledIDs.delete(clientID) })
        }
      }

thanks
