Class weka.gui.GenericObjectEditor 

java.lang.Object
   |
   +----weka.gui.GenericObjectEditor
public class GenericObjectEditor
extends Object
implements PropertyEditor
A PropertyEditor for objects that themselves have been defined as editable in the GenericObjectEditor configuration file, which lists possible values that can be selected from, and themselves configured. The configuration file is called "GenericObjectEditor.props" and may live in either the location given by "user.home" or the current directory (this last will take precedence), and a default properties file is read from the weka distribution. For speed, the properties file is read only once when the class is first loaded -- this may need to be changed if we ever end up running in a Java OS ;-).
