Constructor Details

#initialize(client, room_id, data = {}) ⇒ Room

Note:

This method isn’t supposed to be used directly, rather rooms should be retrieved from the Client abstraction.

Create a new room instance

Parameters:

  • client (Client) —

    The underlying connection

  • room_id (MXID) —

    The room ID

  • data (Hash) (defaults to: {}) —

    Additional data to assign to the room

Options Hash (data):

  • :name (String) —

    The current name of the room

  • :topic (String) —

    The current topic of the room

  • :canonical_alias (String, MXID) —

    The canonical alias of the room

  • :aliases (Array(String, MXID)) —

    All non-canonical aliases of the room

  • :join_rule (:invite, :public, :knock) —

    The join rule for the room

  • :guest_access (:can_join, :forbidden) —

    The guest access setting for the room

  • :world_readable (Boolean) —

    If the room is readable by the entire world

  • :members (Array(User)) —

    The list of joined members

  • :events (Array(Object)) —

    The list of current events in the room

  • :members_loaded (Boolean) —

    If the list of members is already loaded

  • :event_history_limit (Integer) — default: 10 —

    The limit of events to store for the room

  • :avatar_url (String, URI) —

    The avatar URL for the room

  • :prev_batch (String) —

    The previous batch token for backfill

Raises:

  • (ArgumentError)
