org.hibernate.query.criteria.internal.expression.AbstractTupleElement<X>

org.hibernate.query.criteria.internal.expression.SelectionImpl<T>

org.hibernate.query.criteria.internal.expression.ExpressionImpl<X>

org.hibernate.query.criteria.internal.expression.function.ParameterizedFunctionExpression<T>

org.hibernate.query.criteria.internal.expression.function.AggregationFunction<Double>

org.hibernate.query.criteria.internal.expression.function.AggregationFunction.AVG

所有已实现的接口:

Serializable, javax.persistence.criteria.Expression<Double>, javax.persistence.criteria.Selection<Double>, javax.persistence.TupleElement<Double>, FunctionExpression<Double>, ExpressionImplementor<Double>, ParameterContainer, Renderable, SelectionImplementor<Double>, TupleElementImplementor<Double>

封闭类:

AggregationFunction<T>

public static class AggregationFunction.AVG
extends AggregationFunction<Double>

Implementation of a AVG function providing convenience in construction.

Parameterized as Double because thats what JPA states that the return from AVG should be.
