public interface DynamicFeatureA meta-provider for dynamic registration of post-matching providers during an application setup at deployment time. Dynamic feature is used by the runtime to register providers that shall be applied to a particular resource class and method and overrides any annotation-based binding definitions defined on any registered resource filter or interceptor instance.
Providers implementing this interface MAY be annotated with
@Providerannotation in order to be discovered by the runtime when scanning for resources and providers. This provider types is supported only as part of the Server API.

void configure(ResourceInfo resourceInfo, FeatureContext context)A callback method called by the runtime during the application deployment to register provider instances or classes in a
runtime configurationscope of a particular
resource or sub-resource method; i.e. the providers that should be dynamically bound to the method.
The registered provider instances or classes are expected to be implementing one or more of the following interfaces:
A provider instance or class that does not implement any of the interfaces above may be ignored by the API implementation. In such case a
warningmessage must be logged. API implementations may support additional provider contracts that can be registered using a dynamic feature concept.
Conceptually, this callback method is called during a
resource or sub-resource methoddiscovery phase (typically once per each discovered resource or sub-resource method) to register provider instances or classes in a
configurationscope of each particular method identified by the supplied
resource information. The responsibility of the feature is to properly update the supplied
resourceInfo- resource class and method information.
