structHashCode doesn't work so well, either. It also returns false
positives:
<cfset foo = structNew()>
<cfset foo.a.b.c.d = '123'>
<cfset foo.b.c.d = '456'>
<cfoutput>
#createObject("java",
"java.util.Hashtable").init(foo).hashCode()#<br>
#createObject("java",
"java.util.Hashtable").init(foo.a).hashCode()#<br>
#createObject("java",
"java.util.Hashtable").init(foo.a.b).hashCode()#<br>
#createObject("java",
"java.util.Hashtable").init(foo.b).hashCode()#<br>
</cfoutput>
foo.a.b has the same hashCode as foo.b: 67.

Nice, thank you. It'd really be better if I could tell a reference apart
from a copy, but that's probably not possible.
Is there a similar trick for objects?

That's strange, I was getting hashCode() values for structures when I wrote
the dumpstruct tag at work, but now I'm getting 0's at home (both CFMX 6.1).
Anyways, this code should always work, it's just a little slower (fine for
cfdump replacement).
<cfscript>
s = "my String";
writeoutput(s.hashCode() & "<br />");
d = 0.454;
writeoutput(d.hashCode() & "<br />");
st = structNew();
st['s'] = s;
writeoutput(structHashCode(st) & "<br />");
st['d'] = d;
writeoutput(structHashCode(st) & "<br />");
function structHashCode(st) {
return createObject("java", "java.util.Hashtable").init(st).hashCode();
}
</cfscript>
HTH,
Sam
