Hi,
Using a CDI portable extension, I'm registering a custom bean which
represents an interceptor (by implementing the
javax.enterprise.inject.spi.Interceptor interface).
My question now is how to specify the priority of that interceptor.
Intuitively I had expected a method such as Interceptor#getPriority(), but
there isn't such method.
In section 9 the spec says extensions could "override the interceptor order
defined by the @Priority annotation" and refers to section 11.5.2 which
introduces AfterTypeDiscovery#getInterceptors(). So I could use this to add
my interceptor, but I don't see how I could specify the priority while
doing so.
How can this be achieved?
Many thanks,
--Gunnar

Hi Gunnar,
this is not possible. You can only enable the interceptor by adding it
to AfterTypeDiscovery#getInterceptors() relatively to other interceptors.

Hi Jozef,
Thanks for the clarification.
Would it make sense to add Interceptor#getPriority() in a future spec
revision and handle such a custom interceptor bean as if there was an
equivalent annotated interceptor type? As it seems its currently not
possible to achieve the semantics of an annotated interceptor type using a
portable extension.

Yes,
the problem with this is that currently we cannot add a new method to
the interface - otherwise we break existing implementations of the
interface. We can either wait for Java 8 or find some other way of
specifying the priority.

We can either wait for Java 8 or find some other way of specifying the
priority.
One could think about supporting the @Priority annotation on
implementations of j.e.i.s.Interceptor or have a derived interface
PrioritizedInterceptor which adds the new method.
