This interface is called during the evaluation traversal. It aims to produce an evaluation program.
When a node is visited, PreEvaluate is first called on its top trait. It is responsible for forwarding the call to the next trait that implements this interface on the trait stack of the node. Once all traits have had the chance to PreEvaluate, the children of the trait are queried through the IHierarchy interface. The children will then evaluate and PostEvaluate will then be called afterwards on the original trait.
The execution context contains what to evaluate.
