Marks a method in a Dao annotated class as an update method.
 
The implementation of the method will update its parameters in the database if they already exists (checked by primary keys). If they don't already exists, this option will not change the database.
 All of the parameters of the Update method must either be classes annotated with Entity
 or collections/array of it.
