inline objects are an experimental feature in ST/X
(and currently not used by the system).
Inline literal objects are created by the parsers/compilers with the following
syntax:
#{
<slotName1>: value .
<slotName2>: value .
...
}
where each value is a literal, separated by period from the next
i.e. similar to the brace-array construct { expr1 . expr2... }
For every inline object, an anonymous class is created,
providing getters and setters for the slots.
(if literal objects are immutable (which is the default),
no setters are generated)
You cannot add any semantic (i.e. methods) to inline objects -
they are only useful as containers with a nicer protocol
as compared to dictionaries or arrays.
All such created classes will be subclasses of me.
[example:]
|foo|
foo := #{
foo: 'foo value' .
bar: 'bar value' .
baz: 'and obviously: a baz value' .
}.
foo bar.
foo baz.
foo inspect.

accessing
-
setName: newName
-
because classes are shared, multiple uses may try to use different names.
I am anonymous anyway, so the name is only kept for the user's convenience
(i.e. to provide a nicer printString)
Only remember the very first one.
(maybe we should concatenate names instead).
Usage example(s):
|o1 o2|
o1 := InlineObject slotNames:#('foo' 'bar' 'baz' 'bla') values:#(1 2 3 4).
o1 class setName:'myFoo'.
o2 := InlineObject slotNames:#('foo' 'bar' 'baz' 'bla') values:#(1 2 3 4).
o2 class setName:'myFoo2'.
o1 inspect.
o2 inspect.

instance creation
-
values: slotValues
-
return a new inline object instance of myself,
given slot values (must be in my inst-slot order).
I must be the class of an existing concrete inline object,
not the (abstract) InlineObject class itself.
Usage example(s):
|proto protoClass|
proto := InlineObject slotNames:#('foo' 'bar' 'baz') values:#(1 2 3).
protoClass := proto class.
protoClass setName:'Foo'.
(protoClass values:#( 10 20 30 )) inspect.

queries
-
name
-
although inline objects usually have no name, we return something
useful here - there are many places (inspectors) where
a classes name is asked for.
-
nameSpace
-
(comment from inherited method)
should be redefined in concrete subclass(es)
-
package
-
return libbasic, so the methods of my subclass-instances (i.e. the inline objects)
are not seen as extensions in the browser)
