Class CriteriaBuilderImpl.CoalesceImpl<X>

  • All Implemented Interfaces:
    jakarta.persistence.criteria.CriteriaBuilder.Coalesce<X>, jakarta.persistence.criteria.Expression<X>, jakarta.persistence.criteria.Selection<X>, jakarta.persistence.TupleElement<X>, Serializable, InternalExpression, InternalSelection
    Enclosing class:
    CriteriaBuilderImpl
    public class CriteriaBuilderImpl.CoalesceImpl<X>
extends FunctionExpressionImpl<X>
implements jakarta.persistence.criteria.CriteriaBuilder.Coalesce<X>
    Interface used to build coalesce expressions. A coalesce expression is equivalent to a case expression that returns null if all its arguments evaluate to null, and the value of its first non-null argument otherwise.
