Dan Allen commented on CDI-110:
-------------------------------
A more apt title for this JIRA is:
"Provide support for binding an invocation handler to an interface or abstract
class"
The purpose of this feature is to allow interfaces and abstract classes to be
automatically implemented by an invocation handler to which all abstract method
invocations are delegated. The invocation handler would get "bound" to the type
using the same strategy as is used for interceptor binding.
Binding type:
{code:java}
@Target({ METHOD, TYPE })
@Retention(RetentionPolicy.RUNTIME)
@ServiceHandlerBindingType
public @interface EchoService {}
{code}
Invocation handler:
{code:java}
@ServiceHandlerBindingType
@EchoService
public class EchoServiceHandler {
@AroundInvoke
public Object invoke(InvocationContext ctx) {
return ctx.getMethod().getName().toString();
}
}
{code}
Usage:
{code:java}
@EchoService
public interface HelloWorld {
String helloWorld();
}
{code}
Allow injection of abstract classes (Service Handler)

According to mojavelinux:
{quote}
<mojavelinux> service handler, interceptors and decorators are all complementary
<mojavelinux> and cdi is missing the first...which we now realize
{quote}
CDI 1.1 should provide a way to inject abstract classes by specifying a ServiceHandler
