How can I get a list of dirty fields after I have saved an entity?

I Could not find a method like this: AEntity.:GetDirtyFields();

I can only specify the field is dirty or not one by one by using like this: AEntity.FieldName.IsDirty

But if i have many fields?

Can you help me about this subject.

Do you want to set fields to IsDirty, or do you want to get Dirty fields?

Anyway you'll have to loop on the fields to either set the IsDirty flag or to get those which are dirty.
