This sort is guaranteed to be stable: equal elements will + * not be reordered as a result of the sort. * - *

Implementation note: The sorting algorithm is a parallel sort-merge - * that breaks the array into sub-arrays that are themselves sorted and then - * merged. When the sub-array length reaches a minimum granularity, the - * sub-array is sorted using the appropriate {@link Arrays#sort(Object[]) - * Arrays.sort} method. The algorithm requires a working space equal to the - * size of the original array. The {@link - * java.util.concurrent.ForkJoinPool#commonPool() ForkJoin common pool} is - * used to execute any parallel tasks. + *

Implementation note: This implementation is a stable, adaptive, + * iterative mergesort that requires far fewer than n lg(n) comparisons + * when the input array is partially sorted, while offering the + * performance of a traditional mergesort when the input array is + * randomly ordered. If the input array is nearly sorted, the + * implementation requires approximately n comparisons. Temporary + * storage requirements vary from a small constant for nearly sorted + * input arrays to n/2 object references for randomly ordered input + * arrays. + * + *

The implementation takes equal advantage of ascending and + * descending order in its input array, and can take advantage of + * ascending and descending order in different parts of the the same + * input array. It is well-suited to merging two or more sorted arrays: + * simply concatenate the arrays and sort the resulting array. + * + *
