Could InterceptionFactory accept an interface as type parameter --------------------------------------------------------------- Key: CDI-686 URL: https://issues.jboss.org/browse/CDI-686 Project: CDI Specification Issues Issue Type: Clarification Affects Versions: 2.0 .Final Reporter: Antoine Sabot-Durand Assignee: Antoine Sabot-Durand If you take this code: {code:java} @Produces public List<Object> produceList(InterceptionFactory<List<Object>> interceptionFactory) { interceptionFactory.ignoreFinalMethods().configure().filterMethods((m) -> { if (m.getJavaMember().getName().equals("add") && m.getJavaMember().getParameterCount() == 1) { return true; } return false; }).findFirst().get().add(Monitor.Literal.INSTANCE); return interceptionFactory.createInterceptedInstance(new ArrayList<>()); } {code} Parameterized type for injected {{InterceptionFactory}} is an interface {{List<Object>}}, so when calling {{configure()}}, user will work with an {{AnnotatedTypeConfigurator<List<Object>>}} to apply interceptor binding. In a standard interceptor usage, interceptor binding on interface are ignored (even if they have {{@Inherited}} annotation), so doing it with {{InterceptionFactory}} could be confusing for some user.
