Examples of com.espertech.esper.collection.MultiKeyUntyped

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.
