The `ExchangeSubtrip` constructor takes vectors of `IntVar*` (primary and secondary), a function `start_empty_path_class`, and `RoutingIndexPairs`. `DebugString` returns a string representation of the object. `MakeNeighbor` returns a boolean, presumably indicating if a neighboring solution was successfully created. These methods suggest functionalities for defining and exploring neighborhood solutions in routing optimization.\n"]]
