Detailed Description

The column refers to one element of the Db (which can be viewed as an Excel spread sheet). Each variable stands as a column of this table: it is also attached a 'name' (which will serve as the name of the variable) and a possible 'locator' (which characterizes the role of the variable, e.g; coordinate, variable, code, ...). These functions can refer to a single column or to several of them. The columns can be referred to by the variable name, the column index, the internal Id (UID) or the locator.

Parameters

useSel	Option when reading a masked sample: TRUE: the contents of the masked samples is set to TEST FALSE: the masked samples are returned with no impact of the selection
flagCompress	Option when reading a masked sample: TRUE: the returned array is compressed to the only non-masked samples FALSE: the returned array is not compressed
name	Name of the target column
names	Vector of target variable names
locatorType	Type of target locator
iuids	Vector of target user-identified ranks
icols	Vector of Column ranks
icol_beg	Lower bound of the rank interval (included)
icol_end	Upper bound of the rank interval (excluded)
iuid_beg	Lower bound of the user-identification interval (included)
iuid_end	Upper bound of the user-identification interval (excluded)
locatorType	Type of the target locator
locatorIndex	Rank of the item (0-based) for the target locator
flagCompress	When True, the masked values are skipped
