   Construct a column whose i-th row is the i-th element in cells.

   Construct a column whose i-th row is the i-th element in cells. All other rows are NA.

7. implicit def columnMonoid[A]: Monoid[Column[A]]

   

8. def dense[A](values: Array[A], na: Mask = Mask.empty, nm: Mask = Mask.empty): Column[A]

   

   Create a dense column from an array of values.

   Create a dense column from an array of values. A dense column can still have empty values, NA and NM, as specified with the na and nm masks respectively. Dense columns are unboxed and only values that aren't masked by na and nm will ever be returned (so they can be null, NaN, etc.)

   The NM mask (nm) always takes precedence over the NA mask (na). If a row is outside of the range 0 until values.length, then if nm(row) is true, NM will be returned, otherwise NA is returned.

   values

   the values of the column, rows correspond to indices

   na

   masked rows that will return NA

   nm

   masked rows that will return NM

9. def empty[A](nmValues: Mask = Mask.empty): Column[A]

   

   Returns a column that returns NM for any row in nmValues and NA for all others.

   Returns a column that returns NM for any row in nmValues and NA for all others. If all you need is a column that always returns NA, then use Empty.

12. def eval[A](get: (Int) ⇒ Cell[A]): Column[A]

    

    Returns a column whose values are obtained using get.

    Returns a column whose values are obtained using get. Each time a row is accessed, get will be re-evaluated. To ensure values are evaluated only once, you can memoize the column or use on of the *forcing* methods, such as reindex or force.
