Method Detail

sort

public static void sort(int[] a)

Sorts the specified array of ints into ascending numerical order. The sorting algorithm is a tuned quicksort, adapted from Jon L. Bentley and M. Douglas McIlroy's "Engineering a Sort Function", Software-Practice and Experience, Vol. 23(11) P. 1249-1265 (November 1993). This algorithm offers n*log(n) performance on many data sets that cause other quicksorts to degrade to quadratic performance.

Parameters:

a - the array to be sorted

areEqual

public static boolean areEqual(byte[] a,
                               byte[] b)

asList

public static <T> List<T> asList(T... elements)

add

public static <T> T[] add(T obj,
                          T... array)

areEqual

public static boolean areEqual(char[] a,
                               char[] b)

copy

public static byte[] copy(byte[] array,
                          int len)

copy

public static byte[] copy(byte[] array,
                          int offset,
                          int len)

cat

public static byte[] cat(byte[] a,
                         byte[] b)

compare

public static boolean compare(byte[] arr,
                              byte[] arr2)

copy

public static ByteBuffer copy(ByteBuffer buf)
