I created a tree node object, the object can link multiple nodes below it, form a tree.
Will probably use it like this:

 
The root Node *=new Node (index, jv); 
for (int i=0; i <3; I++) 
Node * childLv1=new Node (I, jv); 
Root - & gt; AddChild (childLv1); 
For (int j=0; J & lt; 2; J++) 
Node * childLv2=new Node (j, jv); 
ChildLv1 - & gt; AddChild (childLv2); 

Delete the root; 

 
//h 
The class Node 
{
Public: 
The Node (int, json: : value); 
~ the Node (); 
Int childCount (); 
The child Node * (int index); 
Void addChild (Node *); 
Void setParam (int index, a double value); 
Double getParam (int index); 

NODE_TYPE nodeType; 
Int index; 
Json: : value conf; 

Private: 
STD: : vectorSTD: : vector _params; 
} 
//CPP 
Node: : ~ Node () 
{
for(int i=0; i The delete child (I); 
} 

When I delete a node, I want to destroy it at the same time the following
all child nodesI wrote the destructor right??

CodePudding user response:

Generally true
Write a clear function
Void the clear (Node * & amp; X) {
If (x==nullptr)
return;
for(int i=0; iClear (child (I);


}
X=nullptr.
}
~ the Node () {
For (... )
Clear (child (I);

Do not have what problem, you can also use a global method, hand in a recursive delete the root
