Hi,
Sorry for the newbie question, but I am trying to understand how to
construct and call java dynamically from clojure.
As an example, imagine that there is a bean property called "Bla" and
one wants to set Bla to 1 on object x, which has that property.
So, the objective would be to construct, the following java equivalent
x.setBla(1);
I defined a macro called setProperty like this:
(setProperty "Bla" x 1)
And the definition is (very wrong):
(defmacro setProperty [field obj value]
`(let [cct# (symbol (.concat ".set" ~field))]
(cct# ~obj ~value)
)
)
If I do
(println (setProperty "Bla" x 1))
I get 1 (the setBla is a void, so I should not get 1).
bla is never set to 1, by the way :(
Note that I am not trying to sort the particular case of beans. I am
trying to understand the general mechanism to construct symbols (java
interop) and execute them with a set of parameters over a java object.
Thanks a lot and sorry for the newbie question,
T
