Is there a way of converting dynamically an Entity to a specific
Object ?
For example:
I have some Contact objects and User, Invoice etc, witch are
PersistanceCapable.
So i can make queries (javax.jdo.Query) that return lists of those
kind of objects (Contact, User, Invoice etc) or i can use app engine
datastore.Query to get lists of Entity objects.
1. Is there a simple method of converting an Entity object to a
Contact for example? but without doing smth like :
map = entitiy.getProperties();
Contact c = new Contact();
c.setProperty1(map.get("property1"));
c.setProperty2(....)
... etc
I want to know this because i want to use Query from the
datastore package and not javax.jdo and it doesn't seem a good
solution to make a method for each kind of entity. (I could use java
reflection to create the objects, but i think it is very complicated
since i don't know for example the types of fields and it is probably
a costly method).
2. Is the Query class form app engine datastore package more powerful
(or more suited) than the one from javax.jdo? Witch would you
recommend ?
