Hi,
I'm trying to implement a custom iterator and want to return different
values depending on the method of iteration (for..in or for each..in).
The problem is that my __iterator__ function receives the "onlyKeys"
parameter as being always true regardless of the for loop used.
So in Rhino 1.7 release 2 2009 03 22 on Windoes XP SP3 with Java
1.6.0_13, I have this test case:
var foo = {
__iterator__ : function(onlyKeys) {
print(keys);
yield [0, "a"];
}
};
for each (let f in foo) {}
for (let f in foo) {}
The above will print true for both cases whereas the following (tested
in Firefox 3.0.10) works as expected.
<script type="application/javascript;version=1.7">
var foo = {
__iterator__ : function(onlyKeys) {
alert(keys);
yield [0, "a"];
}
};
for (let f in foo) {}
for each (let f in foo) {}
</script>
Am I doing something wrong or is it a (known) bug? Hopefully, I'm
doing something wrong.
Cheers
Yes, this is a bug. I've just committed a fix to CVS:
ScriptRuntime.java version 1.312.
--N
This fix does not appear to be working. I found out that my array
__iterator__ was broken in Rhino while working on MonkeyScript. I
checked out cvs and testing my code and this code still fails. onlyKeys
is always true even when using for each.
