Path<Y> get(
  String attributeName
)

Create a path corresponding to the referenced attribute.

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

For example:

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

rather than:

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

Parameters:

attributeName - name of the attribute

Returns:

path corresponding to the referenced attribute.

Throws:

IllegalStateException - if invoked on a path that corresponds to a basic type.

IllegalArgumentException - if attribute of the given name does not otherwise exist.
