Represents a scalar/zero-dimensional view on data. 

Views can be created using openView on an IMultiDimData. This method requires a filter that can be created using createFilter (on the IMultiDimData). 

If the resulting IDataView has dimension of zero, it can be cast to an IScalarDataView to gain access to more convenient methods for accessing the scalar data.

class IScalarDataView : virtual public IScalarData, virtual public IDataView;
