Examples

EX1

void TreeNode_AddNode_ex1()
{
    Tree tr;
    TreeNode trNode1 = tr.AddNode("first",  1);        	// Add a sub node named "first" with node ID 1 to tr
    TreeNode trNode2 = trNode1.AddNode("second",  11);	// Add a sub node named "second" with node ID 11 to trNode1
    out_tree(tr); 							

 
    Tree tr1;								
    bool flag1 = tr1.AddNode(trNode1, FALSE); // If the bDeep is FALSE, only add the node trNode1 itself.     
    out_tree(tr1);
    /* 
    Output:
		OriginStorage
		  \---first = 
    */
 
    Tree tr2; 								
    bool flag2 = tr2.AddNode(trNode1, TRUE); // If TRUE, add the node of trNode1 and all its subnodes. 
    out_tree(tr2);
    /* 
    Output:
		OriginStorage
		  \---first
			  \---second = 
    */  
}

EX2

void TreeNode_AddNode_ex2()
{
    Tree tr;
    TreeNode tn1, tn2, tn3;
    tn1 = tr.AddNode("node1", 1);	// Add TreeNode tn1, tn2 to Tree tr. 
    tn2 = tr.AddNode("node2", 2);
    tn3 = tn2.AddNode("node21", 3);	// Add TreeNode tn3 to TreeNode tn2.
    out_tree(tr);
}
