Method Detail

flush

public io.smallrye.mutiny.Uni<java.lang.Void> flush()

Description copied from interface: Mutiny.Session

Force this session to flush asynchronously. Must be called at the end of a unit of work, before committing the transaction and closing the session. Flushing is the process of synchronizing the underlying persistent store with state held in memory.

  session.flush().thenAccept(v -> print("done saving changes"));
 

Specified by:

flush in interface Mutiny.Session

See Also:

EntityManager.flush()

fetch

public <T> io.smallrye.mutiny.Uni<T> fetch(T association)

Description copied from interface: Mutiny.Session

Asynchronously fetch an association that's configured for lazy loading.

  session.fetch(author.getBook()).thenAccept(book -> print(book.getTitle()));
 

Specified by:

fetch in interface Mutiny.Session

Parameters:

association - a lazy-loaded association

Returns:

the fetched association, via a Uni

See Also:

Mutiny.fetch(Object), Hibernate.initialize(Object)

fetch

public <E,T> io.smallrye.mutiny.Uni<T> fetch(E entity,
                                             javax.persistence.metamodel.Attribute<E,T> field)

Description copied from interface: Mutiny.Session

Fetch a lazy property of the given entity, identified by a JPA attribute metamodel. Note that this feature is only supported in conjunction with the Hibernate bytecode enhancer.

  session.fetch(book, Book_.isbn).thenAccept(isbn -> print(isbn))
 

Specified by:

fetch in interface Mutiny.Session

unproxy

public <T> io.smallrye.mutiny.Uni<T> unproxy(T association)

Description copied from interface: Mutiny.Session

Asynchronously fetch an association that's configured for lazy loading, and unwrap the underlying entity implementation from any proxy.

  session.unproxy(author.getBook()).thenAccept(book -> print(book.getTitle()));
 

Specified by:

unproxy in interface Mutiny.Session

Parameters:

association - a lazy-loaded association

Returns:

the fetched association, via a Uni

See Also:

Hibernate.unproxy(Object)

getReference

public <T> T getReference(java.lang.Class<T> entityClass,
                          java.lang.Object id)

Description copied from interface: Mutiny.Session

Return the persistent instance of the given entity class with the given identifier, assuming that the instance exists. This method never results in access to the underlying data store, and thus might return a proxied instance that must be initialized explicitly using Mutiny.Session.fetch(Object).

You should not use this method to determine if an instance exists (use Mutiny.Session.find(java.lang.Class<T>, java.lang.Object) instead). Use this only to retrieve an instance which you safely assume exists, where non-existence would be an actual error.

Specified by:

getReference in interface Mutiny.Session

Parameters:

entityClass - a persistent class

id - a valid identifier of an existing persistent instance of the class

Returns:

the persistent instance or proxy

See Also:

EntityManager.getReference(Class, Object)

getReference

public <T> T getReference(T entity)

Description copied from interface: Mutiny.Session

Return the persistent instance with the same identity as the given instance, which might be detached, assuming that the instance is still persistent in the database. This method never results in access to the underlying data store, and thus might return a proxy that must be initialized explicitly using Mutiny.Session.fetch(Object).

Specified by:

getReference in interface Mutiny.Session

Parameters:

entity - a detached persistent instance

Returns:

the persistent instance or proxy

getLockMode

public org.hibernate.LockMode getLockMode(java.lang.Object entity)

Description copied from interface: Mutiny.Session

Obtain the specified lock level upon the given object. For example, this operation may be used to:

• perform a version check with LockMode.PESSIMISTIC_READ,

                                             AffectedEntities affectedEntities)

Description copied from interface: Mutiny.Session

Create an instance of Mutiny.Query for the given SQL query string, using the given resultType to interpret the results.

• If the given result type is Object, or a built-in type such as String or Integer, the result set must have a single column, which will be returned as a scalar.
• If the given result type is Object[], then the result set must have multiple columns, which will be returned in arrays.
• Otherwise, the given result type must be an entity class, in which case the result set column aliases must map to the fields of the entity, and the query will return instances of the entity.

Any affected entities are synchronized with the database before execution of the query.

Specified by:

createNativeQuery in interface Mutiny.Session

Parameters:

sql - The SQL query

resultType - the Java type returned in each row of query results

affectedEntities - The entities which are affected by the query

Returns:

The Mutiny.Query instance for manipulation and execution

getFlushMode

public org.hibernate.FlushMode getFlushMode()

Description copied from interface: Mutiny.Session

Get the current flush mode for this session.

Returns:

the flush mode

setFlushMode

public Mutiny.Session setFlushMode(org.hibernate.FlushMode flushMode)

setFlushMode in interface Mutiny.Session

Parameters:

flushMode - the new flush mode

Read-only entities are not dirty-checked and snapshots of persistent state are not maintained. Read-only entities can be modified, but changes are not persisted.

Specified by:

setDefaultReadOnly in interface Mutiny.Session

See Also:

Session.setDefaultReadOnly(boolean)

isDefaultReadOnly

public boolean isDefaultReadOnly()

Specified by:

isDefaultReadOnly in interface Mutiny.Session

Returns:

the default read-only mode for entities and proxies loaded in this session
