+ * \param [in] arrBg - the array of ascending values defining the value ranges. The i-th
+ * value of \a arrBg (\a arrBg[ i ]) gives the lowest value of the i-th range,
+ * and the greatest value of the i-th range equals to \a arrBg[ i+1 ] - 1. \a
+ * arrBg containing \a n values defines \a n-1 ranges. The last value of \a arrBg
+ * should be more than every value in \a this array.

+ * This array contains indices of ranges for every value of \a this array. I.e.

+ * belongs to. Or, in other words, this parameter contains for each tuple in \a
+ * this in which cast it holds.
+ * \param [out] rankInsideCast - a new instance of DataArrayInt, of same size as \a this
+ * array, the caller is to delete using decrRef() as it is no more needed.
+ * This array contains ranks of values of \a this array within ranges
+ * they belongs to. I.e. the i-th value of \a rankInsideCast gives the rank of
+ * the i-th value of \a this array within the \a castArr[ i ]-th range, to which
+ * the i-th value of \a this belongs to. Or, in other words, this param contains

+ * \param [out] castsPresent - a new instance of DataArrayInt, containing indices of
