RealmElementQuery

interface RealmElementQuery<T : BaseRealmObject> : Deleteable

RealmQuery

interface RealmQuery<T : BaseRealmObject> : RealmElementQuery<T>

A RealmQuery encapsulates a query on a Realm, a RealmResults or a RealmList instance using the Builder pattern. The query is executed using either find or subscribing to the Flow returned by asFlow.

RealmResults

interface RealmResults<T : BaseRealmObject> : List<T> , Deleteable, Versioned

A Realm Result holds the results of querying the Realm.

RealmScalarNullableQuery

interface RealmScalarNullableQuery<T> : RealmScalarQuery<T?>

Queries that return scalar, nullable values. This type of query is used to more accurately represent the results provided by some query operations, e.g. RealmQuery.min or RealmQuery.max.

RealmScalarQuery

interface RealmScalarQuery<T>

Queries that return scalar values. This type of query is used to more accurately represent the results provided by some query operations, e.g. RealmQuery.count or RealmQuery.sum.

RealmSingleQuery

interface RealmSingleQuery<T : BaseRealmObject> : Deleteable

Query returning a single RealmObject or EmbeddedRealmObject.

Sort

enum Sort : Enum<Sort>

This enum describes the sorting order used in Realm queries.

find

fun <T : BaseRealmObject, R> RealmQuery<T>.find(block: (RealmResults<T>) -> R): R

Similar to RealmQuery.find but it receives a block in which the RealmResults from the query are provided.

fun <T, R> RealmScalarNullableQuery<T>.find(block: (T?) -> R): R

Similar to RealmScalarNullableQuery.find but it receives a block in which the scalar result from the query is provided.

fun <T, R> RealmScalarQuery<T>.find(block: (T) -> R): R

Similar to RealmScalarQuery.find but it receives a block in which the scalar result from the query is provided.

fun <T : BaseRealmObject, R> RealmSingleQuery<T>.find(block: (T?) -> R): R

Similar to RealmSingleQuery.find but it receives a block in which the RealmObject or EmbeddedRealmObject from the query is provided.

max

inline fun <T : Any> RealmQuery<*>.max(property: String): RealmScalarNullableQuery<T>

Similar to RealmQuery.max but the type parameter is automatically inferred.

min

inline fun <T : Any> RealmQuery<*>.min(property: String): RealmScalarNullableQuery<T>

Similar to RealmQuery.min but the type parameter is automatically inferred.

sum

inline fun <T : Any> RealmQuery<*>.sum(property: String): RealmScalarQuery<T>

Similar to RealmQuery.sum but the type parameter is automatically inferred.

TRUE_PREDICATE

const val TRUE_PREDICATE: String

A query filter predicate string that will be true for all objects, hence will make the query select all objects.
