Parameters

[in] column Column.

Sets the content of the vector column by copying from another column. If the code is compiled with the small memory option, and if the source column has not yet been loaded, then we only load the column temporarily for copying purposes and release it again once copying is finished.

void GFitsTableULongCol::nulval ( const unsigned long * value )

Set nul value.

Parameters

[in] value Nul value.

Todo:: To correctly reflect the nul value in the data, the column should be reloaded. However, the column may have been changed, so in principle saving is needed. However, we may not want to store the data, hence saving is also not desired. We thus have to develop a method to update the column information for a new nul value in place ...
