[sdo] [SDO-11]: The Property Resolver is a service providerinterface for abstracting the storage of DataObjects

[Radu Preotiuc-Pietro <radup@bea.com>]

This proposal is a part of SDO Roadmap goal #5 on External Formats.

public interface DataObjectResolver
{
Object get(Object object, Property property, int index);

Object set(Object object, Property property, int index, Object value);

boolean isSet(Object object, Property property);

void unset(Object object, Property property);

boolean isEmpty(Object object, Property property);

int size(Object object, Property property);

boolean contains(Object object, Property property, Object value);

int indexOf(Object object, Property property, Object value);

int lastIndexOf(Object object, Property property, Object value);

void add(Object object, Property property, int index, Object value);

Object remove(Object object, Property property, int index);

Object move(Object object, Property property, int targetIndex, int
sourceIndex);

void clear(Object object, Property property);

Object[] toArray(Object object, Property property);

Object[] toArray(Object object, Property property, Object[] array);

int hashCode(Object object, Property property);

Type getType(Object object); 

DataObject getContainer(Object object); 

Property getContainingProperty(Object object); 

Sequence getSequence(Object object);

DataObject create(Type Type);

void delete(Object object);
}
