public static class AggregationFunction.COUNT extends AggregationFunction<Long>
Long
because thats what JPA states
that the return from COUNT should be.AggregationFunction.AVG, AggregationFunction.COUNT, AggregationFunction.GREATEST<X extends Comparable<X>>, AggregationFunction.LEAST<X extends Comparable<X>>, AggregationFunction.MAX<N extends Number>, AggregationFunction.MIN<N extends Number>, AggregationFunction.SUM<N extends Number>
