Method Details

comesBefore

public boolean comesBefore(short[] x,
 int a,
 int b)

Compare two elements in the given array. This determines the order of the elements in the sorted array.

The default implementation returns true if x[a] < x[b], which sorts the array into ascending order. A subclass can override this method to obtain a different ordering criterion; for example, descending order.

Parameters:

x - Array being sorted.

a - Index of first array element being compared.

b - Index of second array element being compared.

Returns:

True if x[a] comes before x[b] in the desired ordering, false otherwise.

swap

public void swap(short[] x,
 int a,
 int b)

Swap two elements in the given array.

The default implementation swaps x[a] with x[b]. A subclass can override this method to do something different; for example, to swap the elements of other arrays in addition to x.

Parameters:

x - Array being sorted.

a - Index of first array element being swapped.

b - Index of second array element being swapped.
