Abstract Class for all Elements inserted inside a Track.
The TrackElement class is abstract and is used as base class for any element that can be inserted in a Track. It represent the footprint of that element inside the Track (an interval). Additionnaly it keep a pointer to the Track and it's index inside it (Track is implemented with a vector<>
).
To avoid some explicit dynamic cast later, it provides a default implementation for almost all the methods that will be present in all the derived classes. All default methods return false
, NULL
or 0
(zero) or whatever is appropriated to tell it is not meaningful.
Design Note
TrackElement has been designed to serve as a base class for TrackSegment and TrackMarker. But, in the end, those two classes have been put in separated vectors inside the Track, thus rendering this design choice less pertinent. We keep it for now because we may introduce other object than TrackSegment inside a Track. If the need do not arise, we may merge back TrackElement and TrackSegment.
