    - #### AbstractReloadableObjectCreator

          protected AbstractReloadableObjectCreator(PlasticProxyFactory proxyFactory,
                                                    ClassLoader baseClassLoader,
                                                    String implementationClassName,
                                                    org.slf4j.Logger logger,
                                                    OperationTracker tracker)

  - ### Method Detail

    - #### checkForUpdates

          public void checkForUpdates()

      Description copied from interface: `UpdateListener`
      Invoked to force the receiver to check for updates to whatever underlying resources it makes use of.
      Specified by:
        `checkForUpdates` in interface `UpdateListener`

    - #### createObject

          public Object createObject()

      Description copied from interface: `ObjectCreator`
      Create and return the object. In some limited circumstances, the implementation may cache the result, returning the same object for repeated calls.
      Specified by:
        `createObject` in interface `ObjectCreator`

    - #### createInstance

          protected abstract Object createInstance(Class clazz)

      Invoked when an instance of the class is needed. It is the responsibility of this method (as implemented in a subclass) to instantiate the class and inject dependencies into the class.
      See Also:
        `InternalUtils.findAutobuildConstructor(Class)`

    - #### shouldInterceptClassLoading

          public boolean shouldInterceptClassLoading(String className)

      Description copied from interface: `ClassLoaderDelegate`
      Identifies which classes are to be loaded.
      Specified by:
        `shouldInterceptClassLoading` in interface `ClassLoaderDelegate`
      Parameters:
        `className` - fully qualified class name
      Returns:
        true if the class should be intercepted, false to let parent class loader load class

    - #### loadAndTransformClass

          public Class<?> loadAndTransformClass(String className)
                                         throws ClassNotFoundException

      Description copied from interface: `ClassLoaderDelegate`
      Load the class, transforming it as necessary.
      Specified by:
        `loadAndTransformClass` in interface `ClassLoaderDelegate`
      Parameters:
        `className` - binary class name
      Returns:
        loaded and (if not an inner class) transformed class
      Throws:
        `ClassNotFoundException`

    - #### doClassLoad

          public Class<?> doClassLoad(String className)
                               throws IOException

      Throws:
        `IOException`
