Module kdbplus::qninf_base

This module provides a list of q null values. The motivation to contain them in a module is to tie them up as related items rather than scattered values. Hence user should use these indicators with qnull:: prefix, e.g., qninf_base::I.

These values are mainly used to construct K object for api module but underlying values are same for ipc module for simple types. For ipc module, proper negative infinity values of each type are provided under qninf namespace.

Constants

E

Negative infinity value of real.

F

Negative infinity value of float family, i.e., float and datetime.

H

Negative infinity value of short.

I

Negative infinity value of int family, i.e., int, month, date, minute, second and time.

J

Negative infinity value of long family, i.e., long, timestamp and timespan.
