Figure 2.10 KnowledgeWorks System Browser
If you are familiar with LispWorks system definitions, look at the animal demo's "defsystem" file in the editor (choose
KnowledgeWorks > Editor
from the KnowledgeWorks Podium). It contains a
KB-SYSTEM
and a
KB-INIT-SYSTEM
. Examine the components of each system (which can be source files or subsytems) using the System Browser which is available from the Editor via
Meta+X Describe System
or
File > Browse Parent System
.
KB-SYSTEM
s are reloaded when the rules are cleared.
KB-INIT-SYSTEM
s are reloaded when the object base is cleared.
Try this out by finding the KnowledgeWorks Listener and choosing
Memory >
Clear Objects and Rules
. Then reload the system
animal
(type
(load-system "ANIMAL")
into the KnowledgeWorks listener). Both the files
animal-rules
and
animal-objs
are reloaded. Now choose
Memory >
Clear Objects
and reload the
animal
system again and note how only the file
animal-objs
is reloaded.
