Detailed Description

This interface defines a comparator comparing 2 Tracks and returning a negative int, zero, or a positive int if the first track is smaller, equal or greater than the second.

Example: you need to sort a TrackPtrList by Year

First create an implementor for TrackComparator like this:

 class TracksByYearComparator : public TrackComparator {
 public:
     virtual int compare( const itunesdb::Track& track1, const itunesdb::Track& track2 ) {
         return track1.getYear() - track2.getYear();
     }
 };
 

then you call the TrackPtrList::setComparator() method of your TrackPtrList instance and sort() it.
