pre-store method/hook

[Thad Welch <TW...@wyeth.com>]

 
hello,
 
does anyone know how to implement a pre-store method/hook in OJB for
individual domain classes. the pre-store method will be invoked before
OJB's store() and would validate the domain object's data before
database saving. i'm using OJB's cascade save/auto-update feature so
explicitly calling a pre-store method before OJB's store wouldn't cover
all objects saved by cascading. 
 
thanks,
thad

Hi Thad,

let your domain class implement o.a.ojb.broker.PersistenceBrokerAware
and implent the callback methods beforeUpdate and beforeStore.

For details refer to the JavaDoc:

http://db.apache.org/ojb/api/org/apache/ojb/broker/PersistenceBrokerAware.html

cheers,
Thomas
