protected abstract static class DefaultRowSorter.ModelWrapper<M,I> extends Object
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 Object
s and String
s. This allows implementations to provide a custom string converter to be used instead of invoking toString
on the object.
