[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2896) unified approach for id and natural-id loading

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43747#comment-43747 ] 

Steve Ebersole commented on HHH-2896:
-------------------------------------

Initial design swag...

First add 2 new interfaces:
{code}
/**
 * Specifically access by id
 */
public interface IdentifierLoadAccess<T> {
    public IdentifierLoadAccess<T> with(LockOptions lockOptions);

    public T getReference(Object id);
    public T load(Object id);
}

/**
 * Specifically access by natural-key
 */
public interface NaturalIdLoadAccess<T> {
    public NaturalIdLoadAccessT<T> with(LockOptions lockOptions);

    public NaturalIdLoadAccess<T> using(String attributeName, Object value);

    public T getReference();
    public T load();
}
{code}

Eventually, add a method to the above {{NaturalIdLoadAccess}} interface to allow "static type-safe" means for defining values (ala jpa criteria query).


And then add some new methods to {{Session}}:
{code}
    public IdentifierLoadAccess byId(String entityName);
    public <T> IdentifierLoadAccess<T> byId(Class<T> entityClass);
    public NaturalIdLoadAccess byNaturalKey(String entityName);
    public <T> NaturalIdLoadAccess<T> byNaturalKey(Class<T> entityClass);
{code}
