Quantum Meruit has released an update for SortLibrary, bringing it to version 1.4. SortLibrary is a REALbasic library designed for mergesorting in the REALbasic framework. The new version has a more stable mergesort function and allows for user defined comparisons. According to Quantum Meruit:
Version 1.4 of SortLibrary is now available. The main change in 1.4 is to the implementation of mergesort; it now appears to be stable, as it should be. In furtherance of this goal, Iive added a stability test to the test project for mergesort and insertion sort.
SortLibrary is a REALbasic library providing implementations in REALbasic of quicksort, heapsort, mergesort, insertion sort, shell sort, and binary search. For flexbility, SortLibrary uses comparator objects as in the Java Collections Framework to allow you to define your own comparisons.
