Examples of org.apache.hivemind.definition.InterceptorDefinition

org.apache.hivemind.definition.InterceptorDefinition
Defines an interceptor for the methods of a {@link ServicePointDefinition service point}. The interceptor is created by an instance of {@link InterceptorConstructor}. Interceptors are applied in a certain order which bases on the interceptor names. If an implementation of this interface wants to effect the order it must implement the {@link Orderable} interface too. @author Huegen
