Index getAllKnownSubInterface

[olivier dufour]

My need is to get all interface wich extends another interface.
The issue is that index is class oriented. So I can get subclass or class which implement an interface. But I found not solution to get interface which inherit from another.

example

interface A{
}
interface B extends A{
}
interface C extends B{
}

goal is to be abble to get C and B.
I try to use getAllKnownImplementors but it skip interface (I have check source)
I try to do my own method with a recurssive method:

    void produceRecursiveProxies(IndexView index,
            DotName interfaceDN,
            BuildProducer<NativeImageProxyDefinitionBuildItem> proxies) {
        index.getKnownDirectImplementors(interfaceDN).stream()
                .filter(classinfo -> Modifier.isInterface(classinfo.flags()))
                .map(ClassInfo::name)
                .forEach((className) -> {
                    proxies.produce(new NativeImageProxyDefinitionBuildItem(className.toString()));
                    produceRecursiveProxies(index, className, proxies);
                });

    }

but getKnownDirectImplementors seems to not return the interface but only class... not sure ?
Best is to have a new function in indexer for that.

the recurcive is working indeed, it was just that some things was not in the index.
