Construct room state.
Room State represents the state of the room at a given point.
It can be mutated by adding state events to it.
There are two types of room member associated with a state event:
normal member objects (accessed via getMember/getMembers) which mutate
with the state to represent the current state of that room/user, e.g.
the object returned by getMember('@bob:example.com') will mutate to
get a different display name if Bob later changes his display name
in the room.
There are also 'sentinel' members (accessed via getSentinelMember).
These also represent the state of room members at the point in time
represented by the RoomState object, but unlike objects from getMember,
sentinel objects will always represent the room state as at the time
getSentinelMember was called, so if Bob subsequently changes his display
name, a room member object previously acquired with getSentinelMember
will still have his old display name. Calling getSentinelMember again
after the display name change will return a new RoomMember object
with Bob's new display name.
Optional. The ID of the room which has this state. If none is specified it just tracks paginationTokens, useful for notifTimelineSet
Optional. The state of loading out of bound members. As the timeline might get reset while they are loading, this state needs to be inherited and shared when the room state is cloned for the new timeline. This should only be passed from clone.

Private getLooks up a member by the given userId, and if it doesn't exist,

This method makes sure the member is added to the members dictionary
before emitting, as this is done from setStateEvents and setOutOfBandMember.

the id of the user to look up
the membership event for the (new) member. Used to emit.
Get a room member whose properties will not change with this room state. You typically want this if you want to attach a RoomMember to a MatrixEvent which may no longer be represented correctly by Room.currentState or Room.oldState. The term 'sentinel' refers to the fact that this RoomMember is an unchanging guardian for state at this particular point in time.
The member or null if they do not exist.
The room member's user ID.
Private getGet state events from the state of the room.
A list of events if state_key was
undefined, else a single event (or null if no match found).

event of type stateEventType into this room.

The user ID of the user to test permission for
If true, tests if the user may send a state event of this type. Otherwise tests whether they may send a regular event.

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.
