Class AggregationFunction.COUNT

java.lang.Object

org.hibernate.query.criteria.internal.AbstractNode

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.BasicFunctionExpression<X>

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

org.hibernate.query.criteria.internal.expression.function.AggregationFunction<java.lang.Long>

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

All Implemented Interfaces:

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

Enclosing class:

AggregationFunction<T>

public static class AggregationFunction.COUNT
extends AggregationFunction<java.lang.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.
