I don't know what you mean by "parent" or "child endpoints".
If getTargetRef isn't being called, it's because the routing is wrong. If
you want the application or component to send *all* requests to the
redirector, use attachDefault:
router.attachDefault(new MyRedirector(getContext(), ... other args ...);

The point of overriding getTargetRef is to give you the freedom to
determine the target in arbitrary ways, which can be independent of the
template. Here's the code for Redirector:
https://github.com/restlet/restlet-framework-java/blob/master/modules/org.restlet/src/org/restlet/routing/Redirector.java
You can see that the template is only used in getTargetRef. Your overridden
getTargetRef need not use that template. You can just do something like
this:
public class MyRedirector extends Redirector {
final Function<Reference, Reference> targetMapper;
public MyRedirector(Context context, Function<Reference, Reference>
targetMapper, int mode) {
super(context, "<ignored>", mode);
this.targetMapper = targetMapper;
}
protected Reference getTargetRef(Request request, Response response) {
return targetMapper.apply(request.getOriginalRef());
}
}
I'm using Guava's Function type as a shorthand here, to illustrate how the
template can be made irrelevant to the redirection logic, but you can
obviously write this any way you want.
