## cascading.tuple
Interface Comparison<T>

All Known Implementing Classes:
  BytesSerialization

    public interface Comparison<T>

The Comparison interface allows specific underlying type mechanisms to additionally return relevant `Comparator` implementations when required internally.

In the case of Hadoop, `Serialization` implementations that present alternative serialization implementations for custom types manged by `Tuple`s should also implement the `getComparator(Class)` method.

During runtime Cascading can identify and use the correct Comparator during grouping operations if it was not given explicitly on the `Fields.setComparator(Comparable, java.util.Comparator)` family of methods.

See the class `BytesSerialization` for an example.

see cascading.tuple.hadoop.BytesSerialization
