Detailed Description

Get a list of events for this room.

This API returns a list of message and state events for a room. It uses pagination query parameters to paginate history in the room.

Note: This endpoint supports lazy-loading of room member events. See Lazy-loading room members for more information.

Definition at line 17 of file message_pagination.h.

Constructor & Destructor Documentation

◆ GetRoomEventsJob()

Quotient::GetRoomEventsJob::GetRoomEventsJob	(	const QString &	roomId,
		const QString &	dir,
		const QString &	from = `{}`,
		const QString &	to = `{}`,
		std::optional< int >	limit = `std::nullopt`,
		const QString &	filter = `{}`
	)

explicit

Parameters

roomId	The room to get events from.
dir	The direction to return events from. If this is set to `f`, events will be returned in chronological order starting at `from`. If it is set to `b`, events will be returned in reverse chronological order, again starting at `from`.
from	The token to start returning events from. This token can be obtained from a `prev_batch` or `next_batch` token returned by the `/sync` endpoint, or from an `end` token returned by a previous request to this endpoint.

This endpoint can also accept a value returned as a start token by a previous request to this endpoint, though servers are not required to support this. Clients should not rely on the behaviour.

If it is not provided, the homeserver shall return a list of messages from the first or last (per the value of the dir parameter) visible event in the room history for the requesting user.

Parameters

to	The token to stop returning events at. This token can be obtained from a `prev_batch` or `next_batch` token returned by the `/sync` endpoint, or from an `end` token returned by a previous request to this endpoint.
limit	The maximum number of events to return. Default: 10.
filter	A JSON RoomEventFilter to filter returned events with.

Member Function Documentation

◆ begin()

QString Quotient::GetRoomEventsJob::begin ( ) const

inline

A token corresponding to the start of chunk. This will be the same as the value given in from.

Definition at line 67 of file message_pagination.h.

◆ chunk()

RoomEvents Quotient::GetRoomEventsJob::chunk ( )

inline

A list of room events. The order depends on the dir parameter. For dir=b events will be in reverse-chronological order, for dir=f in chronological order. (The exact definition of chronological is dependent on the server implementation.)

Note that an empty chunk does not necessarily imply that no more events are available. Clients should continue to paginate until no end property is returned.

Definition at line 86 of file message_pagination.h.

◆ end()

QString Quotient::GetRoomEventsJob::end ( ) const

inline

A token corresponding to the end of chunk. This token can be passed back to this endpoint to request further events.

If no further events are available (either because we have reached the start of the timeline, or because the user does not have permission to see any more events), this property is omitted from the response.

Definition at line 76 of file message_pagination.h.

◆ makeRequestUrl()

static QUrl Quotient::GetRoomEventsJob::makeRequestUrl	(	const HomeserverData &	hsData,
		const QString &	roomId,
		const QString &	dir,
		const QString &	from = `{}`,
		const QString &	to = `{}`,
		std::optional< int >	limit = `std::nullopt`,
		const QString &	filter = `{}`
	)

static

Construct a URL without creating a full-fledged job object.

This function can be used when a URL for GetRoomEventsJob is necessary but the job itself isn't.

◆ state()

RoomEvents Quotient::GetRoomEventsJob::state ( )

inline

A list of state events relevant to showing the chunk. For example, if lazy_load_members is enabled in the filter then this may contain the membership events for the senders of events in the chunk.

Unless include_redundant_members is true, the server may remove membership events which would have already been sent to the client in prior calls to this endpoint, assuming the membership of those members has not changed.
