public class Jexa

extends Outliner

Jexa: a Java examiner to examine objects via expandable/collapsible outlines.

Jexa may need to be initialized before use. Call Jexa.initialize(); (static initializers aren't always invoked as of Java 1.1.6.)

Standard call to start Jexa is Jexa.examine(Object);

Popup menu on object allows Jexa.mousedObject to be set to the object, so user may navigate through object, then call methods using the object (e.g., using a source code interpreter -- see jevaESUI). Jexa also adds ObjectOutline.outliner to the popup menu.
