. In other words what are the types that would represent the values this projection asked to be pulled into the result set?- Parameters:
criteria
- The local criteria to which this project is attached (for resolution).criteriaQuery
- The overall criteria query instance.- Returns:
- The return types.
- Throws:
HibernateException
- Indicates a problem resolving the types
