_D_e_s_c_r_i_p_t_i_o_n:

     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 'WigTrackLine' (used for Wiggle tracks).
     This class only declares the common elements between the two.

_O_b_j_e_c_t_s _f_r_o_m _t_h_e _C_l_a_s_s:

     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.

_S_l_o_t_s:


     '_n_a_m_e': Object of class '"character"' specifying the name of the
          track. 

     '_d_e_s_c_r_i_p_t_i_o_n': Object of class '"character"' describing the track. 

     '_v_i_s_i_b_i_l_i_t_y': Object of class '"character"' indicating the default
          visible mode of the track, see 'UCSCTrackModes'.

     '_c_o_l_o_r': Object of class '"integer"' representing the track color
          (as from 'col2rgb').

     '_p_r_i_o_r_i_t_y': Object of class '"numeric"' specifying the rank of
          this track. 

_M_e_t_h_o_d_s:


     _a_s(_o_b_j_e_c_t, "_c_h_a_r_a_c_t_e_r") Export line to its string representation.
