23   * <p>Convenient base class for ContainerReflectors. Validates arguments and takes
24   * care of logging and exception handling.  All types of ContainerReflectors
25   * can use this class as a Base, because all methods defined on subinterfaces
26   * of ContainerReflector are supported by this base class.  Note, however, that
27   * this class <em>only</em> states that it implements ContainerReflector so that
28   * subclasses can choose which interfaces they wish to expose.</p>
