@KFStep(category="Tools",
        toolTipText="Sort instances in ascending or descending order")
public class Sorter
extends JPanel
implements BeanCommon, Visible, Serializable, DataSource, DataSourceListener, TrainingSetListener, TestSetListener, InstanceListener, EventConstraints, StructureProducer, EnvironmentHandler

Sorts incoming instances in ascending or descending order according to the values of user specified attributes. Instances can be sorted according to multiple attributes (defined in order). Handles data sets larger than can be fit into main memory via instance connections and specifying the in-memory buffer size. Implements a merge-sort by writing the sorted in-memory buffer to a file when full and then interleaving instances from the disk based file(s) when the incoming stream has finished.
