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

所有已实现的接口:

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

封闭类:

AggregationFunction<T>

public static class AggregationFunction.COUNT
extends AggregationFunction<Long>

Implementation of a COUNT function providing convenience in construction.

Parameterized as Long because thats what JPA states that the return from COUNT should be.
