returns a comparator that compares two arrays of unsigned long valueslexicographically . that is , it compares , using #compare long , long , the first pair of values that follow any common prefix , or when one array is a prefix of the other , treats the shorter array as the lesser . for example , the returned comparator is inconsistent with object #equals object since arrayssupport only identity equality , but it is consistent with arrays #equals long , long . concode_field_sep int[] maxValueMods concode_elem_sep int[] maxSafeDigits concode_elem_sep long[] maxValueDivs concode_elem_sep long MAX_VALUE concode_field_sep long parseUnsignedLong concode_elem_sep long parseUnsignedLong concode_elem_sep int compare concode_elem_sep int compare concode_elem_sep long min concode_elem_sep boolean overflowInParse concode_elem_sep long max concode_elem_sep long divide concode_elem_sep String toString concode_elem_sep String toString concode_elem_sep String join concode_elem_sep long decode concode_elem_sep long flip concode_elem_sep long remainder
