      clazz - The class to analyze for all fields
      Returns:
      The set of all fields on this class (and all subclasses)
    • findPostConstruct

      Method findPostConstruct(Class<?> clazz, Class<?> matchingClass) throws IllegalArgumentException
      Finds the postConstruct method on this class
      Parameters:
      clazz - The class to check for the postConstruct method
      matchingClass - The PostConstruct interface, a small performance improvement
      Returns:
      A matching method, or null if none can be found
      Throws:
      IllegalArgumentException - If a method marked as postConstruct is invalid
    • findPreDestroy

      A matching method, or null if none can be found
      Throws:
      IllegalArgumentException - If a method marked as postConstruct is invalid
    • clean

      void clean(Class<?> clazz)
      Removes this class (and all appropriate sub-classes) from the cache
      Parameters:
      clazz - The class to remove. If null this method does nothing
    • dispose

      void dispose()
      Releases the entire cache, though the ClassReflectionHelper is still usable after calling dispose
