5.5 The Class Browser

Figure 5.5 KnowledgeWorks Class Browser

The Class Browser is obtained by choosing Window > KnowledgeWorks > Classes . It is the same as the LispWorks Class Browser except that

• it appears with an initial focus on standard-kb-object
• when looking at a KnowledgeWorks class the Classes menu and context menu contain an Inspect Instances command which allows you to look at the instances of the class.

This raises an Inspector tool with a list of all the instances.

Figure 5.7 KnowledgeWorks Instances Inspector

Any of the instances displayed in the lower pane may itself be inspected by double-clicking on it.

Other options available in the Class Browser include:

• Superclasses and Subclasses tabs to draw a graphs of the superclasses or subclasses of the class being looked at
• Slots and Initargs tabs to show how the instances can be accessed and initialized.
• Functions tab to show the generic functions or methods defined on this class, either directly or by inheritance

Additionally the Classes menu contains a Browse Metaclass command which browses the class of this class.

Further details can be found in the LispWorks IDE User Guide .
