Listening to object changes #13

Open iammatis opened 5 years ago

Detect attribute changes to an object.

Cat cat = em.find( Cat.class, new Long(69) );
cat.setName("PK");
em.flush();  // changes to cat are automatically detected and persisted

No better way of checking for changes than keeping two separate entity Maps and going through both of them and comparing hashcode(), as of right now.
