CollectionFcts (apache-cassandra API)

java.lang.Object
- org.apache.cassandra.cql3.functions.CollectionFcts

```
public class CollectionFcts
extends java.lang.Object
```
Native CQL functions for collections (sets, list and maps).
All the functions provided here are NativeScalarFunction, and they are meant to be applied to single collection values to perform some kind of aggregation with the elements of the collection argument. When possible, the implementation of these aggregation functions is based on the accross-rows aggregation functions available on AggregateFcts, so both across-rows and within-collection aggregations have the same behaviour.
