Package org.hibernate.engine.jdbc.proxy

Class NClobProxy

java.lang.Object

org.hibernate.engine.jdbc.proxy.ClobProxy

org.hibernate.engine.jdbc.proxy.NClobProxy

All Implemented Interfaces:

Clob, NClob, ClobImplementer, NClobImplementer

@Internal
public class NClobProxy
extends ClobProxy
implements NClob, NClobImplementer

Manages aspects of proxying NClobs for non-contextual creation, including proxy creation and handling proxy invocations. We use proxies here solely to avoid JDBC version incompatibilities.

• ClobProxy
• BlobProxy
• LobCreator
• LobHelper

API Note:

This class is not intended to be called directly by the application program. Instead, use Hibernate.getLobHelper().
