Enumerating possible production chains
The following code shows how to fine control the enumeration process. It enumerates Production Chains for producing User output, reducing the options using a basic query, and then chooses the first one from all possibilities.
// Build a query object xn::Query query; nRetVal = query.SetVendor("MyVendor"); // TODO: check error code query.AddSupportedCapability(XN_CAPABILITY_SKELETON); // TODO: check error code // Enumerate xn::NodeInfoList possibleChains; nRetVal = context.EnumerateProductionTrees(XN_NODE_TYPE_USER, &query, possibleChains, NULL); // TODO: check error code // No errors so far. This means list has at least one item. Take the first one xn::NodeInfo selected = *possibleChains.Begin(); // Create it nRetVal = context.CreateProductionTree(selected); // TODO: check error code // Take the node xn::UserGenerator userGen; nRetVal = selected.GetInstance(userGen); // TODO: check error code // Now we can start to use it
