[infinispan-dev] EntityLoader as interface?

While thinking about EntityLoader as interface (imo, it should be an interface ...), 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"? @Sanne: how would we get just key to be used / loaded, not full entity; e.g GAE has Query::setKeysOnly ... you mentioned some projections -Ales
