* Get the filter or interceptor instance or class that should be bound to the
* particular resource method. May return {@code null}.
*
* The returned provider instance or class is expected to be implementing one
* or more of the following interfaces:
*
*
* - {@link javax.ws.rs.container.ContainerRequestFilter}
* - {@link javax.ws.rs.container.ContainerResponseFilter}
* - {@link ReaderInterceptor}
* - {@link WriterInterceptor}
*
* A provider instance or class that does not implement any of the interfaces
* above is ignored and a {@link java.util.logging.Level#WARNING warning}
* message is logged.
*
*
* If the returned object is a {@link Class Class<P>}, JAX-RS runtime will
* resolve the class to an instance of type {@code P} by first looking at the
* already registered provider instances.
* If there is already a provider instance of the class registered, the JAX-RS
* runtime will use it, otherwise a new provider instance of the class will be
* instantiated, injected and registered by the JAX-RS runtime.
*
*
* In case the resolving the returned provider class to an instance fails for
* any reason, the dynamically bound provider class is ignored and a
* {@link java.util.logging.Level#WARNING warning} message is logged.
*
*
* The method is called during a (sub)resource method discovery phase (typically
* once per each discovered (sub)resource method) to return a filter instance
* that should be bound to a particular (sub)resource method identified by the
* supplied {@link javax.ws.rs.container.ResourceInfo resource information}.
*
*
* @param resourceInfo resource class and method information.
* @return a filter or interceptor instance that should be dynamically bound
* to the (sub)resource method or {@code null} otherwise.
