Overview

Abstract data type

NullableForce is a simple physical quantity type for the dimension LMT^-2. NullableForce is abstract and has two concrete subtypes:

• a Force is an actual value for a physical quantity with a numerical value and a unit of measurement;

• a NullForce is a null value that explicitly indicates the absence of an actual physical quantity.

Subtypes

• Force

• NullForce

Implementation in Proteus Schema

All data attributes with type NullableForce are implemented as DEXPI generic attributes for physical quantities.

Example
