I really want to do something different:
(def x (new StringBuffer "aaaa"))
(doto x (.setLength 2))
But my point is to be able to construct the method name in runtime.
Using doto, I still have the same problem:
(defmacro setProperty [field obj value]
`(let [cct# (symbol (.concat ".set" ~field))]
(doto ~obj (cct# ~value))
)
)
If I do:
(def sb (new StringBuffer "aaaa"))
(setProperty "Length" sb 2)
sb
I get
"aaaa" (It should be "aa").
Again, the point here is to be able to construct method names (full
call signatures, really) on runtime.
I am lost. As in newbie clueless :(
Thanks a lot,
