ByteArrayLexOrder
public ByteArrayLexOrder()
compare
public final int compare(Object obj1,
Object obj2)
- 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 Comparator
- Parameters:
obj1
- first byte array to compare.obj2
- second byte array to compare.- Returns:
- negative number if obj1 < obj2, 0 if obj1 == obj2,
positive number if obj1 > obj2.
- Throws:
ClassCastException
- if either argument is not a byte array.
