Using Java objects as clojure mappings

I have a Java class that I want to use in clojure But I want to use it as a clojure map What steps are required to do this?

I've seen the code for ipersistentmap – does the Java class implement this? Or should there be some clojure code to implement a protocol?

I know I can write some mapping code to explicitly convert code from Java objects to maps, but the solution has a high effort / return Besides, I may encounter the same situation again

Specific example: I have a parser written in Java I want to use it to parse some text and then access the content of the parsed data structure, just as it is in clojure map:

(def parser (new MyParser))

(let [parse-tree (parser ... parse some text ...)]
  ((parse-tree :items) "itemid"))

Solution

The function bean thought of:

Examples from the web site:

user=> (import java.util.Date)
java.util.Date

user=> (def *Now* (Date.))
#'user/*Now*

user=> (bean *Now*)
{:seconds 57,:date 13,:class java.util.Date,:minutes 55,:hours 17,:year 110,:timezoneOffset -330,:month 6,:day 2,:time 1279023957492}
