While thinking about EntityLoader as interface (imo, it should be an

+1, feel free to patch it, but before jumping on it make sure you need
to replace it; I'm not sure of that.
just stumbled upon this:
public List<Object> load(EntityInfo... entityInfos) {
int size = entityInfos.length;
ArrayList<Object> list = new ArrayList<Object>(size);
for (EntityInfo e : entityInfos) {
Object entity = load(e);
if (entity != null) {
list.add(entity);
}
}
return list;
}
We pass "size" into ArrayList.
What if some "entity" is the null, hence not added, will the "list"
size still be ok?
I would say you need to call "trimToSize"?
No that's not needed.
@Sanne: how would we get just key to be used / loaded, not full entity;
e.g GAE has Query::setKeysOnly
... you mentioned some projections
I was referring to the following Hibernate Search capability:
http://docs.jboss.org/hibernate/search/4.2/reference/en-US/html_single/#p...
In short:
org.hibernate.search.FullTextQuery query =
s.createFullTextQuery( luceneQuery, Book.class );
query.setProjection( "id" );
List results = query.list();
But I just realized Infinispan Query doesn't implement _setProjection_ :-(
Open a feature request?
I'd prefer we implement projections over converting the EntityLoader
to an interface.
