        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.

        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.

        Parameters:
        queryString - The SQL query

The given instance does not become associated with the session.

        This operation cascades to associated instances if the association is mapped with CascadeType.MERGE.

        Specified by:
        merge in interface Mutiny.Session
        Parameters:
        entity - a detached instance with state to be copied

        Description copied from interface: Mutiny.Session
        Re-read the state of the given instance from the underlying database. It is inadvisable to use this to implement long-running sessions that span many business tasks. This method is, however, useful in certain special circumstances, for example:
        • where a database trigger alters the object state after insert or update, or

        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,
        • upgrade to a pessimistic lock with LockMode.PESSIMISTIC_WRITE,
        • force a version increment with LockMode.PESSIMISTIC_FORCE_INCREMENT,
        • schedule a version check just before the end of the transaction with LockMode.OPTIMISTIC, or
        • schedule a version increment just before the end of the transaction with LockMode.OPTIMISTIC_FORCE_INCREMENT.

        This operation cascades to associated instances if the association is mapped with CascadeType.LOCK.

        Description copied from interface: Mutiny.Session
        Obtain the specified lock level upon the given object. For example, this operation may be used to:

        • upgrade to a pessimistic lock with LockModeType.PESSIMISTIC_WRITE,
        • force a version increment with LockModeType.PESSIMISTIC_FORCE_INCREMENT,
        • schedule a version check just before the end of the transaction with LockModeType.OPTIMISTIC, or
        • schedule a version increment just before the end of the transaction with LockModeType.OPTIMISTIC_FORCE_INCREMENT.

        This operation cascades to associated instances if the association is mapped with CascadeType.LOCK.

        Specified by:
        lock in interface Mutiny.Session
        Parameters:
        entity - a managed persistent instance

        Description copied from interface: Mutiny.Session
        Set the flush mode for this session.

        The flush mode determines the points at which the session is flushed. Flushing is the process of synchronizing the underlying persistent store with persistable state held in memory.

        For a logically "read only" session, it is reasonable to set the session's flush mode to FlushMode.MANUAL at the start of the session (in order to achieve some extra performance).

        Specified by:
        setFlushMode in interface Mutiny.Session
        Parameters:
        flushMode - the new flush mode

      • setFlushMode

        public Mutiny.Session setFlushMode​(jakarta.persistence.FlushModeType flushModeType)
        Description copied from interface: Mutiny.Session
        Set the flush mode for this session.

        Specified by:
        setFlushMode in interface Mutiny.Session
        Parameters:
        flushModeType - the new flush mode
