  - ### Method Detail

    - #### ultimateTargetClass

          public static Class<?> ultimateTargetClass(Object candidate)

      Determine the ultimate target class of the given instance, traversing not only a top-level proxy but any number of nested proxies as well — as long as possible without side effects.
      Parameters:
        `candidate` - the instance to check (might be a proxy)
      Returns:
        the ultimate target class (or the plain class of the given object as fallback; never `null`)

    - #### isProxy

          public static boolean isProxy(Object object)

      Check whether the given object is a proxy.
      Parameters:
        `object` - the object to check

    - #### isProxyMember

          public static boolean isProxyMember(Member member,
                                              Object object)

      Check whether the given member is a proxy member of a proxy object or is a static proxy member.
      Parameters:
        `member` - the member to check
        `object` - the object to check

    - #### isHibernateProxy

          public static boolean isHibernateProxy(Object object)

      Check whether the given object is a Hibernate proxy.
      Parameters:
        `object` - the object to check

    - #### isHibernateProxyMember

          public static boolean isHibernateProxyMember(Member member)

      Check whether the given member is a member of a Hibernate proxy.
      Parameters:
        `member` - the member to check

    - #### getHibernateProxyTarget

          public static Object getHibernateProxyTarget(Object object)

      Returns:
        the target instance of the given object if it is a Hibernate proxy object, otherwise the given object

    - #### resolveTargetMember

          public static Member resolveTargetMember(Member proxyMember,
                                                   Object target)

      Returns:
        matching member on target object if one exists, otherwise the same member
