# IntegrateChanges(HierarchyCommandList)

> Callback that determines if changes from an update need to be integrated into the hierarchy. IntegrateChanges is called after HierarchyNodeTypeHandlerBase.ChangesPending returns true. When the hierarchy is updated, ChangesPending is called on all registered node ype handlers. If they return true, then IntegrateChanges is called on them. If they return false, then IntegrateChanges is not called on them.
