Overrides org.eclipse.persistence.internal.jpa.querydef.FromImpl.get.

Implements jakarta.persistence.criteria.Path.get.

Doc from jakarta.persistence.criteria.Path.get.

Create a path corresponding to the referenced attribute.

Note

Applications using the string-based API may need to specify the type resulting from the get operation in order to avoid the use of Path variables. 

   For example:

   CriteriaQuery<Person> q = cb.createQuery(Person.class);
   Root<Person> p = q.from(Person.class);
   q.select(p)
    .where(cb.isMember("joe",
                       p.<Set<String>>get("nicknames")));

   rather than:

   CriteriaQuery<Person> q = cb.createQuery(Person.class);
   Root<Person> p = q.from(Person.class);
   Path<Set<String>> nicknames = p.get("nicknames");
   q.select(p)
    .where(cb.isMember("joe", nicknames));
Parameters
attName:String

name of the attribute

Returns:Path<Y>
