```
public Mutiny.Session setFlushMode(FlushMode flushMode)

This operation cascades to associated instances if the association is mapped with CascadeType.REMOVE.
```
 session.delete(book).thenAccept(v -> session.flush());
 
```
Specified by:

remove in interface Mutiny.Session

Parameters:

entity - the managed persistent instance to be removed

See Also:

EntityManager.remove(Object)

setCacheMode
```
public Mutiny.Session setCacheMode(CacheMode cacheMode)

```
Description copied from interface: Mutiny.Session
Create an instance of Mutiny.Query for the given SQL query string, or SQL update, insert, or delete statement. In the case of an update, insert, or delete, the returned Mutiny.Query must be executed using Mutiny.MutationQuery.executeUpdate() which returns an affected row count. In the case of a query:
- If the result set has a single column, the results will be returned as scalars.
- Otherwise, if the result set has multiple columns, the results will be returned as elements of arrays of type Object[].
Any affected entities are synchronized with the database before execution of the statement.
Specified by:

createNativeQuery in interface Mutiny.Session

queryString - The SQL select, update, insert, or delete statement

affectedEntities - The entities which are affected by the statement

getReference
```
public <T> T getReference(Class<T> entityClass,
                          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

refresh
```
public io.smallrye.mutiny.Uni<Void> refresh(Object entity)
```
Description copied from interface: Mutiny.Session
