Hey Gary, thanks for the help
I'm not sure if a type hint would work in this case, as the attribute
expect a class literal, and not a variable of that specific class. Thanks
for the example though, I didn't know that was a valid type hint.
About what I'm trying to do, I'm using a gitlab api gem
(https://github.com/timols/java-gitlab-api), and I need to do some java
interop with it.
I'm trying to get a list of projects filtered by name, but the call java
does doesn't build the search attribute, so I just get all projects, not
filtered by name.
I'm able to get on java by using something like
`connection.retrieve().getAll(buildUrl(project), GitlabProject[].class);`.
The getAll expects a string, and a class literal.
If the return from gitlab wasn't an array, I could just use GitlabProject
on clojure, and that would give me a result. As it's an array, I get an
error showing it can't build a GitlabProject out of ARRAY_START.
My solution to make that call was
(def get-project
(memoize
(fn [project]
(-> connection
.retrieve
(.getAll (build-url project) (array-class-for
GitlabProject))))))
(defn array-class-for [class-name]
(class (make-array class-name 1)))
