Close this session.

Create a Query from a QueryDefinition.

Get the current com.mysql.clusterj.Transaction.

Delete the instance from the database. Only the id field is used to determine which instance is to be deleted. If the instance does not exist in the database, an exception is thrown.

Delete all instances of this class from the database. No exception is thrown even if there are no instances in the database.

Delete all parameter instances from the database.

Find a specific instance by its primary key.

Flush deferred changes to the back end. Inserts, deletes, and updates made when the deferred update flag is true are sent to the back end.

Get a QueryBuilder.

Is this session closed?

Insert the instance into the database. If the instance already exists in the database, an exception is thrown.

Insert the instances into the database.

Mark the field in the object as modified so it is flushed.

Create an instance of an interface that maps to a table.

Insert the instance into the database. This method has identical semantics to makePersistent.

Delete the instance from the database. This method has identical semantics to deletePersistent.

Save the instance in the database without checking for existence. The id field is used to determine which instance is to be saved. If the instance exists in the database it will be updated. If the instance does not exist, it will be created.

Update all parameter instances in the database.

Set the partition key for the next transaction. The key must be of the same type as the primary key defined by the table. The key parameter is the wrapped version of the primitive type of the key, e.g. Integer for INT key types, Long for BIGINT key types, or String for char and varchar types. For multi-column primary keys, the key parameter is an Object[], each element of which is a component of the primary key. The elements must be in the order of primary key declaration.

Update the instance in the database without necessarily retrieving it. The id field is used to determine which instance is to be updated. If the instance does not exist in the database, an exception is thrown.

Update all parameter instances in the database.
