public final class FBCachedClob
extends java.lang.Object
implements java.sql.Clob, java.sql.NClob
This implementation is used for disconnected result sets (ie scrollable and hold cursors over commit).
This class also implements NClob so it can be used with the set/get/updateNClob methods
transparently. It technically does not conform to the JDBC requirements for NClob.
