This is to make oracle and SQL Server compatible, as Oracle stores blank strings as nulls, which makes comparisons on re-materialized objects problematic. author:    Matthew Baird version:    $Id: BlankString2NullFieldConversion.java,v 1.5.2.1 2005/12/21 22:23:38 tomdz Exp $ Method Summary public  Object javaToSql(Object source)      public  Object sqlToJava(Object source)      Method Detail javaToSql public Object javaToSql(Object source)(Code) sqlToJava public Object sqlToJava(Object source)(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
