Class AggregationFunction.AVG

java.lang.Object
  org.hibernate.ejb.criteria.AbstractNode
      org.hibernate.ejb.criteria.expression.AbstractTupleElement<X>
          org.hibernate.ejb.criteria.expression.SelectionImpl<T>
              org.hibernate.ejb.criteria.expression.ExpressionImpl<X>
                  org.hibernate.ejb.criteria.expression.function.BasicFunctionExpression<X>
                      org.hibernate.ejb.criteria.expression.function.ParameterizedFunctionExpression<T>
                          org.hibernate.ejb.criteria.expression.function.AggregationFunction<Double>
                              org.hibernate.ejb.criteria.expression.function.AggregationFunction.AVG

All Implemented Interfaces:

Serializable, Expression<Double>, Selection<Double>, TupleElement<Double>, FunctionExpression<Double>, ExpressionImplementor<Double>, ParameterContainer, Renderable, SelectionImplementor<Double>, TupleElementImplementor<Double>

Enclosing class:

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.
