Hello,
In Jess document for fetch and restore:
r.store("DIMENSION", new java.awt.Dimension(10, 10));
r.eval("(bind ?list (list dimension (fetch DIMENSION)))");
r.eval("(printout t ?list)");
In the second line, what is the "dimension" for between list and
(fetch,
cast to Demension type?
No, there's no casting in Jess. The example is just using the result
of "fetch" as an argument to the "list" function, then binding that
to a variable. The result of the call to "list" is a Jess list of two
elements: the symbol "dimension", and a Dimension object. There's no
special reason why the example does this -- it's just something you
might want to do.
