[Closed] fetch array of node pointers sdk

Mar 20, 2015 6:25 pm

I know array have to have a predefined count when you declare them. So how would I get an amount of objects pointers to use them later? Like in the code below.


 int N_Count = ip->GetSelNodeCount();
  INode *MyNodes[N_Count];
 
  for (int i = 0; i < ip->GetSelNodeCount(); i++){
 		MyNodes[i] = ip->GetSelNode(i);
  }


int N_Count = ip->GetSelNodeCount();
INode *MyNodes;
MyNodes = new INode[N_Count];

for (int i = 0; i < ip->GetSelNodeCount(); i++){
		MyNodes[i] = ip->GetSelNode(i);
}

IMHO in that case it’s better to use classes that support dynamic array sizes like INodeTab, MaxSDK::Array and stl vector (for internal plugin stuff) rather than raw arrays.

INodeTab

    INodeTab nodes;
    for (auto i = 0; i < ip->GetSelNodeCount(); ++i)
        nodes.AppendNode(ip->GetSelNode(i));

MaxSDK::Array

    MaxSDK::Array<INode*> nodes;
    for (auto i = 0; i < ip->GetSelNodeCount(); ++i)
        nodes.append(ip->GetSelNode(i));

stl vector

    std::vector<INode*> nodes;
    for (auto i = 0; i < ip->GetSelNodeCount(); ++i)
        nodes.push_back(ip->GetSelNode(i));

You can also init all these classes with a fixed size (see documentation) so you can do nodes[i] = ip->GetSelNode(i);. That way no reallocation of memory is needed when nodes are appended.

Thanks that works great!
