Data structures and messages are defined by the form:
(glispobjects (< name> < structure> prop ( < messages> ) adj ( < messages> ) isa ( < messages> ) msg ( < messages> ) supers ( < super-classes> ) views ( (< view-name> < view-type> ) ...) ) ... )The class name and structure are necessary. The other items are optional, in any order.
Conventionally, props are properties of the object itself, i.e. have only the object itself as argument and do not have side-effects. adj and isa are boolean predicates on the object itself. msg are general messages, i.e. may have additional arguments and side-effects.
