   String name = field("name").ofType(String.class).in(person).get();

   // Sets the value of the field "name" to "Yoda"
   field("name").ofType(String.class).in(person).set("Yoda");

   // Retrieves the value of the static field "count"
   int count = staticField("count").ofType(int.class).in(Person.class).get();

   // Sets the value of the static field "count" to 3
   field("count").ofType(int.class).in(Person.class).set(3);
