Filters

[Renato Garcia]

 Is there currently any functionality similar to Hibernate filters 
<http://docs.jboss.org/hibernate/core/3.3/reference/en/html/filters.html> in 
JDO?

We've been using this to implement data separation such as Chinese wall 
<http://en.wikipedia.org/wiki/Chinese_wall> and has been proved to be a 
very clean and efficient way to achieve this. Now we to do the same 
thing but using JDO. Any thoughts?

Thanks in advance!
