Hi,
Useful suggestion, semantically.
Syntactically, How about the following:
/**
* User visible persistent states of an entity.
*/
public enum LifeCycleState {NEW, DIRTY, CLEAN, DELETED};
/**
* Gets the persistent types whose instances are in any of the given
lifecycle states in this context.
*/
Set<Class<?>> meta = EntityManager#getClasses(EnumSet<LifyCycleState>
states);
/**
* Gets the persistent entities that are in any of the given lifecycle
states in this context.
*/
Set<Object> instances = EntityManager#getEntities(EnumSet<LifyCycleState>
states, Class<?> classes);

Hi Werner,
I searched in the proposal and in the mailing lists but couldn't find
anything similar.
I'm happy with another solution as well.
