And is guaranteed to be correct vs documentation that may or may not be up to
date!

Well, given they (i.e., NeXT — far as I know, the document's as old as that)
bothered to write the “WebObjects File Format Reference” at all, I presume they
presumed one might need to create/edit those files manually. Which position I
happened to find myself, for the old EOModeler is sorta at the dead side, and
alas, since I have found Eclipse very seriously lacking when compared with
Xcode, I had to write one of my own (https://github.com/jvanek/EOModeler-OSX).
That looks to be the output/input of a EOKeyValueArchiver.
Ha! Thanks a lot: the possibility to test how any particular qualifier might
look like is the second best thing after a perfect documentation :D
All the best,
OC

Hi there,
incidentally, does perhaps anyone know of a reliable documentation of the
property list items which describe an EOFetchSpecification inside of a .fspec
file in a model?
The Apple documentation (“WebObjects File Format Reference”) either blatantly
lies, or I must be doing something terribly wrong; the doc says
===
qualifier / string / A formatted string for an EOQualifier object that
indicates which records or objects the fetch specification should fetch. See
EOQualifier in WebObjects 5.4 Reference for the format of this string.
===
nevertheless, when I tried with a
===
"SharedStaticObjects" = {
class = EOFetchSpecification;
entityName = DBDFList;
fetchLimit = 0;
isDeep = YES;
qualifier = "uid < 99999";
};
===
it simply did not work. Having checked some real .fpecs I have changed it to
===
...
qualifier = {
class = EOKeyValueQualifier;
key = uid;
selectorName = "isLessThan:";
value = {
class = NSNumber;
value = 99999;
};
};
...
===
which works like a charm, but — far as I was able to ascertain — does not seem
to be documented anywhere at all...
Thanks again,
OC
