Class CriteriaQueryImpl<T>

  • All Implemented Interfaces:
    jakarta.persistence.criteria.AbstractQuery<T>, jakarta.persistence.criteria.CommonAbstractCriteria, jakarta.persistence.criteria.CriteriaQuery<T>, Serializable
    public class CriteriaQueryImpl<T>
extends Object
implements jakarta.persistence.criteria.CriteriaQuery<T>, Serializable
    Implementation of Jakarta Persistence Criteria "Query". When the user calls getCompilation() or getParameters(), or toString() then that part of the query is compiled. Any subsequent update will require the compilation to be redone.
