- All Implemented Interfaces:
java.sql.Clob
,java.sql.NClob
public final class FBClob extends java.lang.Object implements java.sql.Clob, java.sql.NClob
Implementation ofClob
.This class also implements
NClob
so it can be used with theset/get/updateNClob
methods transparently. It technically does not conform to the JDBC requirements forNClob
