Description

This method allows you to control which features (TopologyParents) are affected by the next topology graph operation.

Remarks

A topology parent is a feature associated with a topology element (a topology node or topology edge). A parent can have two states; selected or unselected. This state determines if the feature will be affected by the next topology graph operation.

There is a difference between the topology selection and the parent selection. The topology selection is all the selected topology elements (Ex: ITopologyGraph::EdgeSelection or ITopologyGraph::NodeSelection). The parent selection is the state of the parent features and is independent from the topology selection. By default, for a given topology element, all of its parents are selected. However it is possible to explicitly unselect one or more parents so the element is still selected but not all of the parents are. After any operation on the topology graph the parent selection will be reset to default state (all parents selected).
