Column.physical

T physical(T)(size_t i)

The raw accessor: T must be the physical storage type of the dtype (long on the temporal kinds; BOOLEAN and STRING have no scalar physical type - use get!bool and get!string). Null slots return arbitrary bits.

Parameters

`T`	the physical element type, checked against the dtype
`i`	the element index (`0 .. length`)

Returns

the raw stored value.

Throws

DataFrameException when i is out of range or T is not

the physical element type of the dtype.
