Method Detail

compare

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

Perform lexicographical comparison of two byte arrays, regarding each byte as unsigned. That is, compare array entries in order until they differ--the array with the smaller entry is "smaller". If array entries are equal till one array ends, then the longer array is "bigger".

Specified by:

compare in interface java.util.Comparator<byte[]>

Parameters:

bytes1 - first byte array to compare.

bytes2 - second byte array to compare.

Returns:

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

Throws:

ClassCastException - if either argument is not a byte array.
