io.realm

java.lang.Object
io.realm.RealmQuery

A RealmQuery encapsulates a query on a io.realm.Realm or a io.realm.RealmResults using the Builder pattern. The query is executed using either findAll() or findFirst() .

The input to many of the query functions take a field name as String. Note that this is not type safe. If a RealmObject class is refactored care has to be taken to not break any queries.

A io.realm.Realm is unordered, which means that there is no guarantee that querying a Realm will return the objects in the order they where inserted. Use sort(String) (String)} and similar methods if a specific order is required.

A RealmQuery cannot be passed between different threads.

Results are obtained quickly most of the times. However, launching heavy queries from the UI thread may result in a drop of frames or even ANRs. If you want to prevent these behaviors, you can instantiate a Realm using a RealmConfiguration that explicitly sets RealmConfiguration.Builder.allowQueriesOnUiThread(boolean) to false . This way queries will be forced to be launched from a non-UI thread. Alternatively, you can also use findAllAsync() or findFirstAsync() .

findAll

Finds all objects that fulfill the query conditions.Launching heavy queries from the UI thread may result in a drop of frames or even ANRs. We do not recommend doing so and therefore it is not allowed by default. If you want to prevent these behaviors you can obtain a Realm using a RealmConfiguration that explicitly sets RealmConfiguration.Builder.allowQueriesOnUiThread(boolean) to false . This way you will be forced to launch your queries from a non-UI thread, otherwise calls to this method will throw a RealmException . Alternatively, you can use findAllAsync() .

Returns

a io.realm.RealmResults containing objects. If no objects match the condition, a list with zero objects is returned.
