Nested Class Summary
interface	Sort.Compare This interface is used by the `Sort` class to compare elements when an array is being sorted.

Method Summary
static void	qsort(Vector strings) Sort a vector of strings using the Qsort algorithm.
static void	qsort(Object array) Sorts an array of the basic types (ints, floats, bytes, etc.) or Strings.
static void	qsort(Object array, Sort.Compare compare) Sorts an array.

Method Detail

qsort

public static void qsort(Vector strings)

Sort a vector of strings using the Qsort algorithm. The compareTo method of the String class is used for comparison.

Sorts an array of the basic types (ints, floats, bytes, etc.) or Strings. The sort is in increasing order, and is case-sensitive for strings. Sorting an array of booleans or an array of objects other than Strings is not supported.

Parameters: array The array to sort in place.

Throws: IllegalArgumentException if array is not an array of the types listed above.

qsort

public static void qsort(Object array, Sort.Compare compare)

Sorts an array. The specified comparator is used to control the sorting order. Arrays of any type may be sorted, depending upon what the comparator accepts.

Parameters: array The array to sort in place. compare The comparator for sort order.

Throws: IllegalArgumentException if array is not an array.
