Constructors #

The Room object is the result of a subscription request, allowing you to manipulate the subscription itself.

Room(Collection, [options]) #

Arguments	Type	Description
`Collection`	object	an instantiated Kuzzle Collection object
`options`	object	Optional subscription configuration

Options #

Option	Type	Description	Default
`volatile`	JSON Object	Additional information passed to notifications to other users	`null`
`scope`	string	Filter document notifications depending on their scope status. You may receive entering documents (scope: `in`), leaving documents (scope: `out`), all documents changes (scope: `all`) or filter these notifications completely (scope: `none`). This filter does not affect pub/sub messages or user events.	`all`
`state`	string	Filter document notifications depending on the state of the modifying request. You may receive real-time notifications when a document is about to be changed (state: `pending`), or be notified when the change has been fully written in the database (state: `done`), or both (state: `all`). This filter does not affect pub/sub messages or user events.	`done`
`subscribeToSelf`	boolean	(Don't) subscribe to notifications fired as a consequence of our own queries	`true`
`users`	string	Filter user notifications triggered upon a user entering the room (user: `in`), leaving the room (user: `out`), or both (user: `all`). Setting this variable to `none` prevents receiving these notifications	`none`

Properties #

Property name	Type	Description	get/set
`collection`	string	The subscribed collection	get
`filters`	JSON object	The current set of filters of this room	get/set
`headers`	JSON Object	Common headers for all sent documents.	get/set
`volatile`	JSON Object	Additional information passed to notifications to other users	get/set
`subscribeToSelf`	boolean	(Don't) subscribe to notifications fired as a consequence of our own queries	get/set
`roomId`	string	Unique room identifier	get

Notes:

the headers property is inherited from the provided Collection object and can be overridden
updating the volatile property takes effect only after the subscription is renewed
by default, the global volatile properties are sent along with the subscription request. If a volatile option is provided during subscription, it will be merged with the global volatile for the subscription only. In case of conflicts, subscription volatile data takes priority over the global volatile ones.

Usage #

Room room = new Room(dataCollection);
RoomOptions options = new RoomOptions().setSubscribeToSelf(false);
Room room = new Room(dataCollection, options);
