Examples of org.apache.cayenne.access.DataContext.deleteObject()

org.apache.cayenne.access.DataContext.deleteObject()
Schedules an object for deletion on the next commit of this DataContext. Object's persistence state is changed to PersistenceState.DELETED; objects related to this object are processed according to delete rules, i.e. relationships can be unset ("nullify" rule), deletion operation is cascaded (cascade rule). @param object a persistent object that we want to delete. @throws DeleteDenyException if a DENY delete rule is applicable for objectdeletion. @throws NullPointerException if object is null.
