It is also an object which can be named. </p> <p>A reference counting object is any object which has <codeph>CObject</codeph> as its base class. </p> <p>Constructing a <xref href="GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97.dita"><apiname>CObject</apiname></xref> derived type, or calling its <xref href="GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97.dita#GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97/GUID-E6319811-605D-3329-9314-ED25F4A9116C"><apiname>CObject::Open()</apiname></xref> member function, adds a reference to that object by adding one to its reference count. Calling its <xref href="GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97.dita#GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97/GUID-6E50F446-307B-3C9D-9AD6-AFCB49B2F658"><apiname>CObject::Close()</apiname></xref> member function removes a reference by subtracting one from its reference count. When the last user of the object calls <xref href="GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97.dita#GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97/GUID-6E50F446-307B-3C9D-9AD6-AFCB49B2F658"><apiname>CObject::Close()</apiname></xref>, the reference count becomes zero and the object is automatically destroyed. </p> <p>The following drawing shows the idea. </p> <fig id="GUID-18A04428-FBD7-5115-B206-6F2E67343A7F"><image href="GUID-39AAB0D3-6D4D-5DE3-B894-F5E763D3E19B_d0e357614_href.png" placement="inline"/></fig> <p>A <xref href="GUID-9230EF62-376A-389C-B720-7C1EDCB7EA97.dita"><apiname>CObject</apiname></xref> is always part of a class hierarchy.
