Examples of com.espertech.esper.collection.NumberSetPermutationEnumeration

com.espertech.esper.collection.NumberSetPermutationEnumeration
Based on the {@link PermutationEnumeration} this enumeration provides, among a set of supplied integervalues, all permutations of order these values can come in, ie. Example: {0, 2, 3} results in 6 enumeration values ending in {3, 2, 0}.
