org.hibernate.reactive.mutiny

Interface Mutiny.Query<R>

All Known Implementing Classes:

MutinyQueryImpl

Enclosing interface:

Mutiny

public static interface Mutiny.Query<R>

A non-blocking counterpart to the Hibernate Query interface, allowing reactive execution of HQL and JPQL queries. The semantics of operations on this interface are identical to the semantics of the similarly-named operations of Query, except that the operations are performed asynchronously, returning a Uni without blocking the calling thread.

Method Detail

setParameter

Mutiny.Query<R> setParameter(int position,
                             java.lang.Object value)

setParameter

Mutiny.Query<R> setParameter(java.lang.String name,
                             java.lang.Object value)

setParameter

<T> Mutiny.Query<R> setParameter(javax.persistence.Parameter<T> name,
                                 T value)

setMaxResults

Mutiny.Query<R> setMaxResults(int maxResults)

setFirstResult

Mutiny.Query<R> setFirstResult(int firstResult)

getSingleResult

io.smallrye.mutiny.Uni<R> getSingleResult()

Asynchronously Execute this query, returning a single row that matches the query, or null if the query returns no results, throwing an exception if the query returns more than one matching result.

Returns:

the single resulting row or null

See Also:

Query.getSingleResult()

getResultList

io.smallrye.mutiny.Uni<java.util.List<R>> getResultList()

Asynchronously execute this query, return the query results as a List. If the query contains multiple results per row, the results are returned in an instance of Object[].

Returns:

the resulting rows as a List

See Also:

Query.getResultList()

executeUpdate

io.smallrye.mutiny.Uni<java.lang.Integer> executeUpdate()

Asynchronously execute this delete, update, or insert query, returning the updated row count.

Returns:

the row count as an integer

See Also:

Query.executeUpdate()

setReadOnly

Mutiny.Query<R> setReadOnly(boolean readOnly)

Set the read-only/modifiable mode for entities and proxies loaded by this Query. This setting overrides the default setting for the persistence context.

See Also:

Mutiny.Session.setDefaultReadOnly(boolean)

setComment

Mutiny.Query<R> setComment(java.lang.String comment)

Set the comment for this query.

Parameters:

comment - The human-readable comment

setCacheMode

Mutiny.Query<R> setCacheMode(org.hibernate.CacheMode cacheMode)

(Re)set the current CacheMode in effect for this query.

getCacheMode

org.hibernate.CacheMode getCacheMode()

Obtain the CacheMode in effect for this query. By default, the query inherits the CacheMode of the Mutiny.Session from which is originates.

See Also:

Mutiny.Session.getCacheMode()

setLockMode

Mutiny.Query<R> setLockMode(java.lang.String alias,
                            org.hibernate.LockMode lockMode)

Set the LockMode to use for specified alias (as defined in the query's FROM clause).

Query.setLockMode(String,LockMode)
