  * <h3>Replacing Nodes at Run Time</h3>

+ * 
  * <p>
- * The structure of the Truffle tree can be changed at run time by replacing nodes using the {@link Node#replace(Node)}
- * method. This method will automatically change the child pointer in the parent of the node and replace it with a
- * pointer to the new node.
