Assignment operator.
<p>
This overloaded variant is provided for the sole purpose of setting a <a class="el" href="class_DOM_Node.html">DOM_Node</a> reference variable to zero. Nulling out a reference variable in this way will decrement the reference count on the underlying Node object that the variable formerly referenced. This effect is normally obtained when reference variable goes out of scope, but zeroing them can be useful for global instances, or for local instances that will remain in scope for an extended time, when the storage belonging to the underlying node needs to be reclaimed.<dl compact><dt>
