Properties | |
| FIRApp * | app |
| BOOL | persistenceEnabled |
| dispatch_queue_t | callbackQueue |
The entry point for accessing a Firebase Database. You can get an instance by calling [FIRDatabase database]. To access a location in the database and read or write data, use [FIRDatabase reference].
| + (FIRDatabase *) databaseForApp: | (database(app:)) | NS_SWIFT_NAME |
Gets an instance of FIRDatabase for a specific FIRApp.
| app | The FIRApp to get a FIRDatabase for. |
| - (void) goOffline |
Shuts down our connection to the Firebase Database backend until goOnline is called.
| - (void) goOnline |
Resumes our connection to the Firebase Database backend after a previous goOffline call.
| + (database() NS_SWIFT_NAME |
Gets the instance of FIRDatabase for the default FIRApp.
| - (void) purgeOutstandingWrites |
The Firebase Database client automatically queues writes and sends them to the server at the earliest opportunity, depending on network connectivity. In some cases (e.g. offline usage) there may be a large number of writes waiting to be sent. Calling this method will purge all outstanding writes so they are abandoned.
All writes will be purged, including transactions and onDisconnect writes. The writes will be rolled back locally, perhaps triggering events for affected event listeners, and the client will not (re-)send them to the Firebase Database backend.
| - (FIRDatabaseReference *) reference |
Gets a FIRDatabaseReference for the root of your Firebase Database.
| - (FIRDatabaseReference *) referenceFromURL: | (NSString *) | databaseUrl |
Gets a FIRDatabaseReference for the provided URL. The URL must be a URL to a path within this Firebase Database. To create a FIRDatabaseReference to a different database, create a FIRApp} with a FIROptions object configured with the appropriate database URL.
| url | A URL to a path within your database. |
| - (FIRDatabaseReference *) referenceWithPath: | (NSString *) | path |
Gets a FIRDatabaseReference for the provided path.
| path | Path to a location in your Firebase Database. |
| + (NSString *) sdkVersion |
Retrieve the Firebase Database SDK version.
| + (void) setLoggingEnabled: | (BOOL) | enabled |
Enables verbose diagnostic logging.
| enabled | YES to enable logging, NO to disable. |
|
readnonatomicweak |
The FIRApp instance to which this FIRDatabase belongs.
|
readwritenonatomicstrong |
Sets the dispatch queue on which all events are raised. The default queue is the main queue.
Note that this must be set before creating your first Database reference.
|
readwritenonatomicassign |
The Firebase Database client will cache synchronized data and keep track of all writes you've initiated while your application is running. It seamlessly handles intermittent network connections and re-sends write operations when the network connection is restored.
However by default your write operations and cached data are only stored in-memory and will be lost when your app restarts. By setting this value to YES, the data will be persisted to on-device (disk) storage and will thus be available again when the app is restarted (even when there is no network connectivity at that time). Note that this property must be set before creating your first Database reference and only needs to be called once per application.
