Hi,
Derby engine uses Dependency Manager to keep track of object dependencies and depedent objects get notified when the provider object has some notifications to send. I understand this at the high level but I wondered if someone for familiar with the implementation can provide some more details. For instance, there are methods like prepareToInvalide, makeInvalid and makeValid in the Dependent interface. What is the difference between prepareToInvalide and makeInvalid and in what order these methods get called? Is there a difference between dependencies maintained in memory vs dependencies maintained over Derby reboots?
I am looking into revoke privileges which needs to fire actions to objects dependent on privileges and any info on Depedency manager will be useful.
thanks,
Mamta
