Private _currentReadonly clientReadonly idWhether or not we need to fetch the initial set of events for the thread. We can only do this if the server has support for it, so if it doesn't we just pretend that we've already fetched them.
Private lastThe last event in this thread, if we don't yet have this in the timeline.
When we run processRootEvent (which I think happens during the
setting-up of the thread), we set this to the event pointed to by the
server in latest_event 1 that came through with the thread root.
Later, when we have populated the timeline, this is set to undefined, so that methods like replyToEvent fall through to use lastReply, which looks in the timeline for the latest event that is a "thread reply" i.e. directly refers to the thread root with an m.thread relation.
So it looks like this is only really relevant when initialEventsFetched is false, because as soon as the initial events have been fetched, we should have a timeline (I think).
If all replies in this thread are redacted, this is set to the root event. I'm not clear what the meaning of this is, since usually after the initial events have been fetched, lastEvent should be undefined. In fact, the whole usage inside onRedaction looks suspect - it may be that we were thinking lastEvent always refers to the actual last event, but it only does so before initialEventsFetched becomes true.
The usage of lastEvent inside onEcho looks suspicious, since I'd think we probably mean replyToEvent there - we are trying not to echo a duplicate event, and we probably want that behaviour even after initialEventsFetched has become true.

Internal TEMPORARY. Only call this when MSC3981 is not available, and we have some late-arriving events to insert, because we recursively found them as part of populating a thread. When we have MSC3981 we won't need it, because they will all be supplied by the homeserver in one request, and they will already be in the right order in that response. This is a copy of addEventToTimeline above, modified to call insertEventIntoTimeline so this event is inserted into our best guess of the right place based on timestamp. (We should be using Sync Order but we don't have it.)

No checks are made to see if the listener has already been added. Multiple calls
passing the same combination of event and listener will result in the listener

By default, event listeners are invoked in the order they are added. The TypedEventEmitter#prependListener method can be used as an alternative to add the event listener to the beginning of the listeners array.

Reset the live timeline of all timelineSets, and start new ones.
This is used when /sync returns a 'limited' timeline. 'Limited' means that there's a gap between the messages /sync returned, and the last known message in our timeline. In such a case, our live timeline isn't live anymore and has to be replaced by a new one. To make sure we can continue paginating our timelines correctly, we have to set new pagination tokens on the old and the new timeline.
Optional backPaginationToken: null | stringtoken for back-paginating the new timeline
Optional forwardPaginationToken: null | stringtoken for forward-paginating the old live timeline, if absent or null, all timelines are reset, removing old ones (including the previous live timeline which would otherwise be unable to paginate forwards without this token). Removing just the old live timeline whilst preserving previous ones is not supported.

Typed Event Emitter class which can act as a Base Model for all our model and communication events. This makes it much easier for us to distinguish between events, as we now need to properly type this, so that our events are not stringly-based and prone to silly typos.
Type parameters:
Events- List of all events emitted by thisTypedEventEmitter. Normally an enum type.Arguments- A ListenerMap type providing mappings from event names to listener types.SuperclassArguments- TODO: not really sure. Alternative listener mappings, I think? But only honoured for.emit?
