<DIV><FONT size=2>This won't work. The image side equivalent of stObjectat()
is #basicAt: and NOT #at: as one might expect. That's because when you use
stObjectat() the primitive code which is equivalent to #basicAt: is being
executed.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The bottom line here is: Don't ever use complex composite
objects in primitives (OrderedCollection, Stream, etc) - only use primitive
forms (Integer, Array) as far far as possible. It's simple to handle on
the image side (instead of "self doPrimitivieWith: foo" just use "self
doPrimitiveWith: foo asArray") and it's terribly hard to deal with the
complexities from the primitives.</FONT></DIV>

<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>i am trying to access some string literals in a
smalltalk OrderedCollection that is passed as an arg to a named
primtive.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>in smalltalk:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> primMyPrimitive:
anOrderedCollectionOfStrings</FONT></DIV>
<DIV><FONT face=Arial size=2>
<primtive:'primMyPrimitive' module:'foo'></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>the c source:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> EXPORT(int)
primMyPrimitive(void) {</FONT></DIV>
<DIV><FONT face=Arial size=2> </FONT></DIV>
<DIV><FONT face=Arial size=2> int
collectionOop, strElementOop;</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>
collectionOop = interpreterProxy->stackObjectValue(0);</FONT></DIV>
<DIV><FONT face=Arial size=2>
strElementOop = interpreterProxy->stObjectat(collectionOop,
1);</FONT></DIV>
<DIV><FONT face=Arial size=2>}</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>now i know there is data at index 1, but this
method is erroring out in squeak. i am writing the c source myself. is there
some sort of cast i need to do with the origianl collectionOop in order for
it to work with stObjectat? does stObjectat not know that collectionOop
represents an OrderedCollection? i just want to be able to get the oops of
the elements in the OrderedCollection, i would know how to extract the
string values once i got them, problem is i cannot get the
oops.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>i would certainly appreciate any
help.</FONT></DIV>
