Description
-----------

Base class for anything that keeps a reference count. Resource and many other helper objects inherit this. References keep an internal reference counter so they are only released when no longer in use.

.. _class_Reference_init_ref:

- :ref:`bool<class_bool>`  **init_ref**  **(** **)**

.. _class_Reference_reference:

- void  **reference**  **(** **)**

Increase the internal reference counter. Use this only if you really know what you are doing.

.. _class_Reference_unreference:

- :ref:`bool<class_bool>`  **unreference**  **(** **)**

Decrease the internal reference counter. Use this only if you really know what you are doing.
