Hibernate version: 3 rc1

Name and version of the database you are using:Oracle 8.1.7

I would like to implement the Interceptor interface but I haven't found in hibernate docs the default values for the getEntity and getEntityName methods

What must I use as default values?

thanks in advanced.

Sambuko.

It really depends on your implementation. If you provide more details as to what you are looking to use the Interceptor for, we can help you out.

hello mveitas

I would like to implement Interceptor interface in order to assign value for two date columns: "Creation" and "LastUpdate".

I have seen hibernate reference documentation and I have found the following example:

package org.hibernate.test;

import java.io.Serializable;
import java.util.Date;
import java.util.Iterator;

import org.hibernate.Interceptor;
import org.hibernate.type.Type;

public class AuditInterceptor implements Interceptor, Serializable {

private int updates;
private int creates;

public void onDelete(Object entity,
Serializable id,
Object[] state,
String[] propertyNames,
Type[] types) {
// do nothing
}

public boolean onFlushDirty(Object entity,
Serializable id,
Object[] currentState,
Object[] previousState,
String[] propertyNames,
Type[] types) {

if ( entity instanceof Auditable ) {
updates++;
for ( int i=0; i < propertyNames.length; i++ ) {
if ( "lastUpdateTimestamp".equals( propertyNames[i] ) ) {
currentState[i] = new Date();
return true;
}
}
}
return false;
}

public boolean onLoad(Object entity,
Serializable id,
Object[] state,
String[] propertyNames,
Type[] types) {
return false;
}

public boolean onSave(Object entity,
Serializable id,
Object[] state,
String[] propertyNames,
Type[] types) {

if ( entity instanceof Auditable ) {
creates++;
for ( int i=0; i<propertyNames.length; i++ ) {
if ( "createTimestamp".equals( propertyNames[i] ) ) {
state[i] = new Date();
return true;
}
}
}
return false;
}

public void postFlush(Iterator entities) {
System.out.println("Creations: " + creates + ", Updates: " + updates);
}

public void preFlush(Iterator entities) {
updates=0;
creates=0;
}

...

}

After thar I have seem the API documentation and JavaDoc for org.hibernate.Interceptor interface and I haven't found out the default values for those methods.

Could you help me?

Thanks in advanced.

Return either null or false in Interceptor methods that you do not care to implement.

I vote for an InterceptorAdapter BTW.

Sounds like a great Wiki thing...

looks good ;)

There is the EmptyInterceptor that is a static final class in org.hibernate.cfg.Configuration. Why no expose this to the world?
