Interface FetchGroupBuilder<T>

public interface FetchGroupBuilder<T>

Builds a FetchGroup by adding fetch clauses.

We add select() and fetch() clauses to define the object graph we want to load.

 FetchGroup fetchGroup = FetchGroup
   .select("name, status")
   .fetch("contacts", "firstName, lastName, email")
   .build();

 Customer.query()
   .select(fetchGroup)
   .where()
   ...
   .findList();
