Re: $'s in java class member names and set!
Yeah. I tried that but it gives what you expect:
Class A defined as follows:
package projects.test;
public class A
{
public boolean y;
public boolean $z;
}
REPL:
user= (import '(projects.test A))
projects.test.A
user= (def m (A.))
#'user/m
user= (set! (. m y) true)
true
user= (set! (. m $z) true)
java.lang.IllegalArgumentException: No matching field found:
_DOLLARSIGN_z for class projects.test.A
(NO_SOURCE_FILE:0)
user= (def klass (.getClass m))
#'user/klass
user= (def fields (.getFields klass))
#'user/fields
user= (.getName (aget fields 0))
y
user= (.getName (aget fields 1))
$z
user=
Just so everyone knows this isn't a trumped up example. If I can make
this work then I can instantiate JavaFX classes directly without using
JavaFX reflection. I'm exploring a Clojure cover library for JavaFX.
Incidently, some of you might be interested in this:

Stephen Chin will presenting a talk at JavaOne about using other JVM
languages to call JavaFX.

Is there a special syntax for handling java members with $'s in their
names?- Hide quoted text -

Re: $'s in java class member names and set!
That's probably due to a problem with clojure.core/munge I recently reported on the Dev list [1] -- see a proposed patch attached to my first e-mail in that thread. I notice there still hasn't been any response to that issue... I think I'm just going to go ahead an open a ticket for this tonight.

Re: $'s in java class member names and set!
I suspect $ is in munge because Rich and company may want to use it as a special reader character. $'s used to access inner classes work fine. I'd be fine with that as long as there's still a way to access Java identifiers with dollar signs (perhaps a special macro).

Try using reflection to print out what the JVM thinks the field's name
is. This might help.
