All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.event.ActionListener, java.awt.event.AdjustmentListener, java.util.EventListener, java.awt.image.ImageObserver, java.awt.event.ItemListener, java.awt.MenuContainer, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.io.Serializable

Direct Known Subclasses:

DefaultDataGenerator

public abstract class DataGenerator

extends ShowNetworkMap

implements java.awt.event.AdjustmentListener

Abstract controller applet for the computation of network-based spatiotemporal datasets. The abstract methods allow to use user-defined classes determining the bahavior of the generator. Non-abtract subclasses are the classes generator2.DefaultDataGenerator, generator2.OracleDataGenerator, and generator2.OracleSpatialDataGenerator. It is also possible to run these subclasses as Java applications. See the additional documentation for the supported properties in the property file.
