//! \brief Get events and state around the specified event.
//!
//! This API returns a number of events that happened just before and
//! after the specified event. This allows clients to get the context
//! surrounding an event.
//!
//! *Note*: This endpoint supports lazy-loading of room member events. See
//! [Lazy-loading room members](/client-server-api/#lazy-loading-room-members) for more information.

public:
    //! \param roomId
    //!   The room to get events from.
    //!
    //! \param eventId
    //!   The event to get context around.
    //!
    //! \param limit
    //!   The maximum number of context events to return. The limit applies
    //!   to the sum of the `events_before` and `events_after` arrays. The
    //!   requested event ID is always returned in `event` even if `limit` is
    //!   0. Defaults to 10.
    //!
    //! \param filter
    //!   A JSON `RoomEventFilter` to filter the returned events with. The
    //!   filter is only applied to `events_before`, `events_after`, and
    //!   `state`. It is not applied to the `event` itself. The filter may
    //!   be applied before or/and after the `limit` parameter - whichever the
    //!   homeserver prefers.
    //!
    //!   See [Filtering](/client-server-api/#filtering) for more information.
