38 * Typically this should be used with a Boost instrusive pointer,
39 * instead of calling Reference() and Unreference() methods directly.
46 * @brief Increment the object's reference count.
51 * @brief Decrement the object's reference count.
53 * When the reference count drops to zero, the object will self-destruct.
58 * @brief Retrieve the object's reference count.
60 * @return The reference count
67 * @brief Default constructor.
72 * @brief RefObject is intended as a base class.
74 * A RefObject may only be deleted when its reference count is zero.
79 * @brief Copy constructor.
81 * The newly copied object will have a reference count of zero.
