Kai Grabfelder commented on IBATIS-594:
---------------------------------------

so value objects implementing the new interface would called after beeing 
instanziated. And what kind of action would you do in the implementation of 
postProcessCallback(Object[] results). Maybe I'll understand the need for this 
change better if you attach a new unit test that is using the new functionality.

> add object post processing capabilities to iBatis after objects have been 
> populated from the recordset.
> We have found the need to set fields within business objects after they have 
> been read from a database using iBatis. Up until now we have been using the 
> row handler callback, however, when using iBatis lazy loading, this does no 
> longer suffice.
> To counter this we have added an interface to the iBatis package to allow for 
> any implementors to be called after the object has been created and populated.
