com.espertech.esper.collection.MultiKeyUntyped
Functions as a key value for Maps where keys need to be composite values. The class allows a Map that uses MultiKeyUntyped entries for key values to use multiple objects as keys. It calculates the hashCode from the key objects on construction and caches the hashCode.

        Object[] values = new Object[criteriaEvaluators.length];
        for (int i = 0; i < criteriaEvaluators.length; i++)
        {
            values[i] = criteriaEvaluators[i].evaluate(eventsPerStream, true, agentInstanceContext);
        }
        return new MultiKeyUntyped(values);
