Re: casting error

I have a wonky work-around. The file that is aot compiled depends on the file with the defrecord reference. I eliminated the direct dependency and exported a function that does an alter-root-var. So the provider injects the required value into the dependent. On Wednesday, July 16, 2014 9:33:52

Re: casting error

That does, in fact, fix the compile issue. Thanks! The cast error, however, persists. It's something to do with reloading the namespace with the defrecord. Once it happens, it takes a "lein clean" to clear. After that it works w/o error until the namespace is reloaded. It's something to do with

Re: Critiques of "my-flatten" which uses CPS

Interesting - thank you! Good to know about "into" as a way to achieve a non-lazy concat - in conjunction with a vector. I like your accumulator version - morphing the structure of the input as you go to achieve the desired result. I've come up with another version, that passes through both a

Try fully qualifying the class name in the return type hint. Might be the same symptom as in this ticket: http://dev.clojure.org/jira/browse/CLJ-1232 Andy On Wed, Jul 16, 2014 at 7:18 PM, Brian Craft wrote: > Apparently this is due to a class loader problem. > > I moved it into a different fi

Re: casting error

Apparently this is due to a class loader problem. I moved it into a different file to try to avoid the problem. However I'm now finding that nothing referencing foo will compile, throwing this error: CompilerException java.lang.IllegalArgumentException: Unable to resolve classname: PStatement

casting error

Trying to eliminate a reflection warning, I put a type hint on a function, like (defn foo ^PStatement [] ...) which compiles without the reflection warnings, but at run time I get ClassCastException java.lang.ClassCastException: cavm.h2.PStatement cannot be cast to cavm.h2.PStatement What doe

Re: NPE on ((print))

Hi, Parenthesis are for function invocations in Clojure. ((print)) calls the result of print (which is null) aka. nil, which results in a NPE. Thanks, Ambrose On Thu, Jul 17, 2014 at 1:20 AM, wrote: > Hi! > > user=> ((print)) > NullPointerException user/eval1 (NO_SOURCE_FILE:1) > >

handling only a part of a hash-map

Hi, I'm just beginning with clojure. ;(let [conn (mg/connect) ; db (mg/get-db conn "throughput") ; coll "clojure_throughput_src"] ;;; with a query, as Clojure maps ; ( doseq [item (mc/find-maps db coll {})] ;(println ; (get_timeslot ;(get_dt ; ( get item :ts))
