57 // TSMCoordColumn handles a coordinate column for a Tiled
58 // Storage Manager.
59 // </etymology>
60 
61 // <synopsis>
62 // TSMCoordColumn is used by
63 // <linkto class=TiledStMan>TiledStMan</linkto>
64 // to handle the access to
65 // a table column containing coordinates of a tiled hypercube axis.
66 // There are 2 types of coordinates (as described at
67 // <linkto class=TableDesc:defineHypercolumn>
68 // TableDesc::defineHypercolumn</linkto>):
69 // <ol>
70 // <li> As a vector. These are the coordinates of the arrays held
71 // in the data cells. They are accessed via the get/putArray
72 // functions. Their shapes are dependent on the hypercube shape,
73 // so it is checked if they match.
74 // <li> As a scalar. These are the coordinates of the extra axes
75 // defined in the hypercube. They are accessed via the get/put
76 // functions.
77 // </ol>
78 // The coordinates are held in a TSMCube object. The row number
79 // determines which TSMCube object has to be accessed.
80 // <p>
81 // The creation of a TSMCoordColumn object is done by a TSMColumn object.
82 // This process is described in more detail in the class
83 // <linkto class=TSMColumn>TSMColumn</linkto>.
84 // </synopsis>
85 
86 // <motivation>
87 // Handling coordinate columns in the Tiled Storage Manager is
88 // different from other columns.
