Pass .class to Clojure Function when .class is called on a Java interface

Question

I need to pass .class for a Java interface to a function call in Clojure.

Calling (class ) requires an instance of the object, where as I want the static class name.

Basically so I can java interop and use: keysetHandle.getPrimitive(Aead.class);

Passing Aead but Aead is only an interface want it like so but cannot work out how to get the equivalent Aead.class in Clojure?

(.getPrimitive keyset-handle Aead.class)

Have you tried (.getPrimitive keyset-handle Aead)?

You should be able to pass the class of your interface just by using its name. An example Java class:

public class Foo {
    public <P> String bar(Class<P> klass) {
        return klass.getCanonicalName();
    }
}

Then in a REPL, using the java.util.List interface for example:

user=> (import Foo)
Foo
user=> (.bar (Foo.) java.util.List)
"java.util.List"
