  • Method Details

    • getHierarchy

      public static <T> List<Class<? super T>> getHierarchy(Class<T> clazz, Filter... filters)
      Gets the elements of the hierarchy of the given class which match the given filters. Classes are added by starting with the class itself and its implemented interfaces. Then its super class and interfaces are added and so on.
      Type Parameters:
      T - the type of the class
      Parameters:
      clazz - the class for which to retrieve the hierarchy
      filters - filters applying for the search
      Returns:
      List of hierarchy classes. Will only contain those types matching the given filters. The list contains the given class itself, if it is no proxy class.

    • getDirectlyImplementedInterfaces

      public static <T> Set<Class<? super T>> getDirectlyImplementedInterfaces(Class<T> clazz)
      Gets all interfaces (and recursively their super-interfaces) which the given class directly implements. Interfaces implemented by super-classes are not contained.
      Type Parameters:
      T - the type of the class
      Parameters:
      clazz - the class for which to retrieve the implemented interfaces
      Returns:
      Set of all interfaces implemented by the class represented by this hierarchy. The empty list is returned if it does not implement any interfaces.
