Thanks Lars but there is no difference...when i try to load my namespace
I get this output:
Clondie24.core=> (load-file "src/Clondie24/core.clj")
#'Clondie24.core/-mainReflection warning,
/home/sorted/clooJWorkspace/Clondie24/src/Clondie24/core.clj:104 - call
to setLocation can't be resolved.
Reflection warning,
/home/sorted/clooJWorkspace/Clondie24/src/Clondie24/core.clj:122 - call
to setLocation can't be resolved.
Reflection warning,
/home/sorted/clooJWorkspace/Clondie24/src/Clondie24/core.clj:206 -
reference to field getListPosition can't be resolved.
Reflection warning,
/home/sorted/clooJWorkspace/Clondie24/src/Clondie24/core.clj:251 - call
to update_position can't be resolved.
Of the 4 warnings only the last 2 can be justified (it is not
predetermined what type comes in)...the first 2 refer to 2 different
records that do the same thing as far as updating the position goes and
setLocation is the culprit again!

Hi again (busy day eh?),
well this doesn't make any sense either! Why is a record with type-hinted
arguments still using reflection?
I've got the following example record:
--------------------------------------------------------------------------------------------------
(defrecord CheckersPiece [^java.awt.Color color
^java.awt.Point position
rank]
Piece
(update-position [this np] ;mutable state inside Point!
(. position setLocation ;can accept ints or doubles
(first np) (second np))) ;np should be [x, y]
(die [this] (vary-meta this assoc :dead true)) ;communicate death
through meta-data
(promote [this] (make-checker color position :rank 'prince)) ; a checker is
promoted to prince
(getGridPosition [this] (vector (.getX position) (.getY position)))
(getListPosition [this] (translate-position (first (.getGridPosition
this))
(second (.getGridPosition
this)) board-mappings-checkers))
(getPoint [this] position)
(getMoves [this] nil) ;TODO
Object
(toString [this]
(println "Checker (" rank ") at position:" (.getListPosition this) " ->"
(.getGridPosition this))) )
---------------------------------------------------------------------------------------------------------------------------
and whenever i call update-position it complains that setLocation cannot be
resolved. setLocation is a method in java.awt.Point so i don't see why this
happens!
Would (.setLocation position) possibly behave differently maybe? Worth a try?
Ehh... With the two arguments I forgot to include in the call obviously..
