The Evaluate callback is where a custom ICENode performs the main computation. The Evaluate callback uses the ICENodeContext object to get the input and output port data.
| Note | The user data stored in BeginEvaluate or Init is always accessible from the Evaluate callback. However, unless the custom node threading mode is single-threading, the Context::PutUserData property cannot be used from the Evaluate callback. |
