About the ColumnVariant class

Variables  Properties  Methods  

Implements Serializable, Cloneable

This class extends the borland.jbcl.util.Variant class by adding a getter to obtain the DataSet and Column information for a Variant. For example, if a method is given a variable v that is defined as a Variant, you can use code such as


if (v instanceof ColumnVariant)
to determine if the Variant variable is part of a DataSet. If it is part of a DataSet, it can display any errors from the MaskableTextItemEditor in the status bar.
