The RowVersion type represents a 64 bit integer value.
This is identical to the <CLASS>BigInt</CLASS> data type with the exception a property of type RowVersion has special meaning to the Object and SQL filers.
A property/field of type RowVersion will increment a namespace-wide counter located at ^rINDEXEXT("rv"), and that incremented value will be stored in the RowVersion property/field for each INSERT, UPDATE, or Save that occurs on the class/table. A RowVersion property/field is typically used to enforce concurrency for the row/object.
Only one property/field per class/table may be defined with type RowVersion.
A property/field of type RowVersion may not be a property of the IdKey index.
A property/field of type RowVersion may not have a value explicitly set by an INSERT or UPDATE statement or Save call.
The Library.RowVersion class is Final, and cannot be subclassed.
