Description

An object representing a "track line" in the UCSC format. There are two concrete types of track lines: BasicTrackLine (used for most types of tracks) and GraphTrackLine (used for graphical tracks). This class only declares the common elements between the two.

Objects from the Class

Objects can be created by calls of the form new("TrackLine", ...) or parsed from a character vector track line with as(text, "TrackLine"). But note that UCSC only understands one of the subclasses mentioned above.
