class vtkWeakPointer< T ></h3>
a weak reference to a <a class="el" href="a01084.html" title="abstract base class for most VTK objects">vtkObject</a>.
<p>
<a class="el" href="a01869.html" title="a weak reference to a vtkObject.">vtkWeakPointer</a> is a weak reference to a <a class="el" href="a01084.html" title="abstract base class for most VTK objects">vtkObject</a> which means that assigning a <a class="el" href="a01084.html" title="abstract base class for most VTK objects">vtkObject</a> to the <a class="el" href="a01869.html" title="a weak reference to a vtkObject.">vtkWeakPointer</a> does not affect the reference cound of the <a class="el" href="a01084.html" title="abstract base class for most VTK objects">vtkObject</a>. However, when the <a class="el" href="a01084.html" title="abstract base class for most VTK objects">vtkObject</a> is destroyed, the <a class="el" href="a01869.html" title="a weak reference to a vtkObject.">vtkWeakPointer</a> gets initialized to NULL, thus avoid any dangling references.
