How to use defrecord getBasis to look up record instance field values
defrecord Person [name age company])
(def p1 {:name "foo", :age 27, :company :bar})
(map #(% p1) (keys p1))
("foo" 27 :bar)
user=> (map #(% p1) (Person/getBasis))
(nil nil nil nil)
user=> (map #(class %) (Person/getBasis))
(clojure.lang.Symbol clojure.lang.Symbol clojure.lang.Symbol
clojure.lang.Symbol)
getBasis seems to return the symbol but my record lookup technique doesnt
seem to be working..
any idea why
I dont wish to use keys on the record instance since the instance might be
missing some fields in the record

Re: How to use defrecord getBasis to look up record instance field values
Maybe you are looking for something like this?
(map #(% p1) (map keyword (Person/getBasis)))
keyword can take a symbol as argument, and return a corresponding keyword.
