  org.apache.hivemind.annotations.internal.AnnotatedModuleProcessor

public class AnnotatedModuleProcessor
extends java.lang.Object

Does the work for AnnotatedModuleReader. Processes an annotated class and registers the defined extension and extension points in a registry definition. The construction of extension points and extensions bases on reflective method calls to an instance of the module class. The module instance is created by a ModuleInstanceProvider during registry construction.
