[Pljava-dev] Question regarding triggers and data visibility

[Burtenshaw, John J.]

Thanks Rakesh.  I found a couple of mailing lists that suggest putting the results to a collection which should be simple enough.  I'm sure this will work fine for me!

Regards,
John Burtenshaw

I do not know any other convenient way to pass the information.  I  
think the easiest way is to create a transfer object.  If you have  
created PGobject sub-classes to represent your data, then you already  
have it.  If not, just create a custom transfer object and pass that  
to the RMI object.  You can also pass custom strings, or XML if  
performance is not an absolute must.  You can easily create the  
transfer object or String representation from the information in the  
Trigger.
