Detailed Description

ValueRange is an abstract range implementation that stores variant values.

ValueRange is intended for use within bindings, so it has an assignment interface to the range. There is no capability for PropertyObject storage, as PropertyObject cannot be a result of a mathematical binding operation and also not a valid property data type.

Since: Kanzi 3.9.0
