Interface IndexComparator


  • public interface IndexComparator
    A comparator that is used within BlockIntegerList that compares two int values which are indices to data that is being compared. For example, we may have an BlockIntegerList that contains indices to cells in the column of a table. To make a sorted list, we use this comparator to lookup the index values in the list for sorting and searching.
