我有以下代码:
(use 'clojure.java.io)
(defrecord Member [id name salary role])
(defrecord Role [id name])
(def member-records (ref ()))
(defn add-member [member]
(dosync (alter member-records conj member)))
;;Test-data -->
(def dev-r(->Role 1 "Developer"))
(def test-member1(->Member 1 "Kirill" 70000.00 dev-r))
;;Test-data <--
(defn save-data-2-file []
(with-open [wrtr (writer "C:/Platform/Work/test.cdf")]
(print-dup @member-records wrtr)))
(defn process-line [line]
(println line))
;;Test line content
;;#BTC.pcost.Member{:id 1, :name "Kirill", :salary 70000.0, :role #BTC.pcost.Role{:id 1, :name "Developer"}})
(defn load-data-from-file []
(with-open [rdr (reader "C:/Platform/Work/test.cdf")]
(doseq [line (line-seq rdr)]
(process-line line))))
我想在读取文件后重新创建记录,但我不明白我是如何做到的。是的,我知道我可以解析文本并通过解析行的元素填充我的结构,但这会很困难,因为我有很多像“成员”和“角色”这样的结构。任何人都可以建议我一种方法,我可以做到吗?
