+This function only does a \emph{shallow} comparison, i.e. it doesn't compare

-Destructor.
+Destructor. It's declared {\tt protected} so that wxObjectRefData instances will never

\constfunc{int}{GetRefCount}{\void}
Returns the reference count associated with this shared data.
-When this goes to zero during a \helpref{wxObject::UnRef}{wxobjectunref}, an object
-can delete this {\bf wxObjectRefData} object.
+When this goes to zero during a \helpref{DecRef}{wxobjectrefdatadecref} call, the object

+\membersection{wxObjectRefData::DecRef}\label{wxobjectrefdatadecref}
+
+\func{void}{DecRef}{\void}
+
+Decrements the reference count associated with this shared data and, if it reaches zero,
+destroys this instance of wxObjectRefData releasing its memory.
+
+Please note that after calling this function, the caller should absolutely avoid to use
+the pointer to this instance since it may not be valid anymore.

+
+\func{void}{IncRef}{\void}
+
+Increments the reference count associated with this shared data.
