AbstractOptionaloptions: EventEmitterOptionsAbstracttimelineAdd a temporary local-echo receipt to the room to reflect in the client the fact that we've sent one.
The user ID if the receipt sender
The event that is to be acknowledged
The type of receipt
the receipt is unthreaded
AbstractaddSynchronously calls each of the listeners registered for the event named
event, in the order they were registered, passing the supplied arguments
to each.
The name of the event to emit
Rest...args: Parameters<SuperclassArguments[T]>Arguments to pass to the listener
true if the event had listeners, false otherwise.

Returns true if the event had listeners, false otherwise.
import EventEmitter from 'node:events';
const myEmitter = new EventEmitter();
// First listener
myEmitter.on('event', function firstListener() {
console.log('Helloooo! first listener');
});
// Second listener
myEmitter.on('event', function secondListener(arg1, arg2) {
console.log(`event with parameters ${arg1}, ${arg2} in second listener`);
});
// Third listener
myEmitter.on('event', function thirdListener(...args) {
const parameters = args.join(', ');
console.log(`event with parameters ${parameters} in third listener`);
});
console.log(myEmitter.listeners('event'));
myEmitter.emit('event', 1, 2, 3, 4, 5);
// Prints:
// [
// [Function: firstListener],
// [Function: secondListener],
// [Function: thirdListener]
// ]
// Helloooo! first listener
// event with parameters 1, 2 in second listener
// event with parameters 1, 2, 3, 4, 5 in third listener
Rest...args: Parameters<Arguments[T]>Similar to emit but calls all listeners within a Promise.all and returns the promise chain
The name of the event to emit
Rest...args: Parameters<SuperclassArguments[T]>Arguments to pass to the listener
true if the event had listeners, false otherwise.
Rest...args: Parameters<Arguments[T]>AbstractfindLook in this room/thread's timeline to find an event. If this is a
room, we look in all threads, but if this is a thread, we look only
inside this thread.
This issue should also be addressed on synapse's side and is tracked as part of https://github.com/matrix-org/synapse/issues/14837
Retrieves the read receipt for the logged in user and checks if it matches the last event in the room and whether that event originated from the logged in user. Under those conditions we can consider the context as read. This is useful because we never send read receipts against our own events
the logged in user
Get the ID of the event that a given user has read up to, or null if:
(The event might not exist if it is not loaded, and the thread ID might not match if the event has moved thread because it was redacted.)
The user ID to get read receipt event ID for
If true, return only receipts that have been sent by the server, not implicit ones generated by the JS SDK.
ID of the latest existing event that the given user has read, or null.
AbstractgetReturns the most recent unthreaded receipt for a given user
the MxID of the User
an unthreaded Receipt. Can be undefined if receipts have been disabled or a user chooses to use private read receipts (or we have simply not received a receipt from this user yet).
Gets the latest receipt for a given user in the room
The id of the user for which we want the receipt
Whether to ignore synthesized receipts or not
Optional. The type of the receipt we want to get
the latest receipts of the chosen type for the chosen user
Get a list of receipts for the given event.
the event to get receipts for
A list of receipts with a userId, type and data keys or an empty list.
AbstractgetGet a list of user IDs who have read up to the given event.
the event to get read receipts for.
A list of user IDs.
AbstracthasDetermines if the given user has read a particular event ID with the known history of the room. This is not a definitive check as it relies only on what is available to the room at the time of execution.
The user ID to check the read state of.
The event ID to check if the user read.
True if the user has read the event, false otherwise.
Returns the number of listeners listening to the event named event.
The name of the event being listened for
Returns a copy of the array of listeners for the event named event.
Alias for removeListener
Adds the listener function to the end of the listeners array for the
event named event.
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
being added, and called, multiple times.
By default, event listeners are invoked in the order they are added. The prependListener method can be used as an alternative to add the event listener to the beginning of the listeners array.
a reference to the EventEmitter, so that calls can be chained.
Adds a one-time listener function for the event named event. The
next time event is triggered, this listener is removed and then invoked.
Returns a reference to the EventEmitter, so that calls can be chained.

a reference to the EventEmitter, so that calls can be chained.
Returns a copy of the array of listeners for the event named eventName,
including any wrappers (such as those created by .once()).
Removes all listeners, or those of the specified event.
It is bad practice to remove listeners added elsewhere in the code,
particularly when the EventEmitter instance was created by some other
component or module (e.g. sockets or file streams).
Optionalevent: EventEmitterEvents | EventsThe name of the event. If undefined, all listeners everywhere are removed.
a reference to the EventEmitter, so that calls can be chained.
Removes the specified listener from the listener array for the event named event.
a reference to the EventEmitter, so that calls can be chained.
Abstractset
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?
