Method Detail

parseStringArrayIntoLongArray

static long[] parseStringArrayIntoLongArray(java.lang.String[] strings)

validateLongs

static void validateLongs(long[] longs)

mergeLongArrayIntoIPv6Address

static IPv6Address mergeLongArrayIntoIPv6Address(long[] longs)

inHighRange

static boolean inHighRange(int shortNumber)

expandShortNotation

static java.lang.String expandShortNotation(java.lang.String string)

rewriteIPv4MappedNotation

static java.lang.String rewriteIPv4MappedNotation(java.lang.String string)

Replaces a w.x.y.z substring at the end of the given string with corresponding hexadecimal notation. This is useful in case the string was using IPv4-Mapped address notation.

countOccurrences

public static int countOccurrences(java.lang.String haystack,
                                   char needle)

generateZeroes

public static java.lang.String generateZeroes(int number)

isLessThanUnsigned

static boolean isLessThanUnsigned(long a,
                                  long b)

prefixWithZeroBytes

static byte[] prefixWithZeroBytes(byte[] original,
                                  int newSize)
