Variables  Constructors  Properties  Methods  

Implements Serializable, Cloneable

This class extends the com.borland.dx.dataset.Variant class by adding two methods to retrieve DataSet and Column information associated with this value.

Visual components that receive values from a DataSet will receive them as ColumnVariant. These components can test the Object value received in order to collect more contextual information about the value.
