Cloning a node

What's the best way to copy a node?

Under the Introduction to Some Simple Classes: General Copy Functions I read about the clone function. Is that the best way?

Try this approach:

Code: Select all

DSL_node *origNode = net.GetNode(hOrig);
int hNew = net.AddNode(origNode->Definition()->GetType(), "ClonedNode");
const DSL_intArray &parents = net.GetParents(hOrig);
for (int i = 0; i < parents.NumItems(); i++)
{
	net.AddArc(parents[i], hNew);
}
net.GetNode(hNew)->Definition()->Clone(*origNode->Definition());
net.GetNode(hNew)->ExtraDefinition()->Clone(*origNode->ExtraDefinition());

For historical reasons, the complete copy requires the "extra definiton" to be cloned along with node definition. This object contains diagnosis-specific data.

This is very cool.

I actually wanted to copy a node without the arcs.

Thanks for the post.
