Map with Enum as Key in a Qute Template

[cdhermann]

Dear Quarkus community,

does anybody know if and how it is possible in a Qute template to query a value from a Map when the key is an Enum?

Example:

package a.b.c;

public enum Test {
    VAL1, VALS
}

var map = new HashMap<Test, String>();

In the Qute template neither map.get(Test.VAL1) nor map.get(VAL1) or map.get(a.b.c.Test.VAL1) is working.

At the moment I work around the issue by defining the HashMap as new HashMap<String, String>. In my opinion, this removes a lot of "compile time safety".

You help is apreciated.

You can annotate your enum with @TemplateEnum and use something like map.get(Test:VAL1). If you don't control the source of the enum you'd need to implement a template extension method like this: https://github.com/quarkusio/quarkus/blob/main/extensions/qute/deployment/src/test/java/io/quarkus/qute/deployment/extensions/NamespaceTemplateExtensionTest.java#L110-L113.

@mkouba thank you very much. It works.

It is also in the docs. But, until you answer here I lacked the brain power to relate this to my issue.
