Class NClobProxy

java.lang.Object

org.hibernate.engine.jdbc.ClobProxy

org.hibernate.engine.jdbc.NClobProxy

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

public class NClobProxy
extends ClobProxy

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

Generated proxies are typed as Clob (java.sql.NClob extends Clob) and in JDK 1.6+ environments, they are also typed to java.sql.NClob
