Class BytesComparator

java.lang.Object

cascading.tuple.hadoop.util.BytesComparator

All Implemented Interfaces:

cascading.tuple.Hasher<byte[]>, cascading.tuple.StreamComparator<BufferedInputStream>, java.io.Serializable, java.util.Comparator<byte[]>

public class BytesComparator
extends java.lang.Object
implements cascading.tuple.StreamComparator<BufferedInputStream>, cascading.tuple.Hasher<byte[]>, java.util.Comparator<byte[]>, java.io.Serializable

Class BytesComparator is used to compare arrays of bytes.

Note that BytesComparator implements Hasher, but for the Hasher interface to be applied during grouping, sorting or joining, it must be set on a Fields instance via Fields.setComparator(Comparable, java.util.Comparator).
