DefaultRowSorter.ModelWrapper JDK 1.6)

Description

protectedabstractstatic abstract class DefaultRowSorter.ModelWrapper

DefaultRowSorter.ModelWrapper is responsible for providing the data that gets sorted by DefaultRowSorter.

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.
