(Quick Reference)



Retrieve the names of modified fields in a domain class instance.


def b = Book.get(1)

def names = b.dirtyPropertyNames
for (name in names) {
    def originalValue = b.getPersistentValue(name)


This method is useful mostly for audit logging or other work done in a beforeUpdate event callback. Hibernate caches the original state of all loaded instances for dirty checking during a flush and this method exposes the names of modified fields so you can compare them with the current state.
