public final int compare(byte[] bytes1, byte[] bytes2)

Implements java.util.Comparator.compare.

Parameters
bytes1:byte[]

first byte array to compare.

bytes2:byte[]

second byte array to compare.

Returns:int

negative number if bytes1 < bytes2, 0 if bytes1 == bytes2, positive number if bytes1 > bytes2.
