Member Typedef Documentation

using UN_DataNumber::ValueIntType = exint

A numerical value for indexing into data containers and for unique IDs to validate of data objects.

An enum class ValueType and UN_DataNumber should be interchangeable. UN_DataNumber really just provides methods to operate on it and the ability to "derive" from it. In particular, it should be possible to implicitly cast ValueType to UN_DataNumber class type. It should be possible to implicitly cast this UN_DataNumber class type to ValueType since it is an enum class, and therefore not implicitly castable to other types such as exint or int (and therefore deemed "safe" without the risk of data narrowing).

Member Data Documentation

constexpr ValueType UN_DataNumber::INVALID_NUMBER = ValueType(-1)

static

A numerical value for an invalid data object number. It is used in initialization to denote a non-existent, invalid, or an unknown data object. The value of -1 is consistent in its use as an index into data arrays.
