Class Overview
DefaultRowSorter.ModelWrapper is responsible for providing
the data that gets sorted by DefaultRowSorter. You
normally do not interact directly with ModelWrapper.
Subclasses of DefaultRowSorter provide an
implementation of ModelWrapper wrapping another model.
For example,
TableRowSorter provides a ModelWrapper that
wraps a TableModel.
ModelWrapper makes a distinction between values as
Objects and Strings. This allows
implementations to provide a custom string
converter to be used instead of invoking toString on the
object.

public String getStringValueAt (int row, int column)
Returns the value as a String at the specified
index. This implementation uses toString on

override this method should never return null.

- the value at the specified index as a
String
Throws
