7 \class SOPHYA::SwFitsDataTable
8 \ingroup FitsIOServer
9 This class can be used to organize data in table (row-column) form.
10 Each column holds homogeneous data (same data type), while different
11 columns can be used for different data types
12 (integer, float, string ...).
13 A Fits file binary table is used as swap space.
14
15 \warning
16 - When creating a table, the output fits file (FitsInOutFile) must not be closed
17 (destroyed) before the SwFitsDataTable object is destroyed. The destructor writes
18 out any pending buffer to the fits file.
19 - It is not possible to make a complete (deep) copy of a SwFitsDataTable
20 Copy constructor and equal operator shares the data.
