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"],null,["# ExchangeSubtrip\n\nC++ Reference: class ExchangeSubtrip\n====================================\n\n\nNote: This documentation is automatically generated.\n\n| Method ||\n|--------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [`DebugString`](https://github.com/google/or-tools/blob/v9.4/ortools/constraint_solver/routing_neighborhoods.h#L768) | Return type: `std::string ` \u003cbr /\u003e |\n| [`ExchangeSubtrip`](https://github.com/google/or-tools/blob/v9.4/ortools/constraint_solver/routing_neighborhoods.h#L763) | \u003cbr /\u003e Arguments: `const std::vector\u003cIntVar*\u003e& vars, const std::vector\u003cIntVar*\u003e& secondary_vars, std::function\u003cint(int64_t)\u003e start_empty_path_class, const RoutingIndexPairs& pairs` \u003cbr /\u003e |\n| [`MakeNeighbor`](https://github.com/google/or-tools/blob/v9.4/ortools/constraint_solver/routing_neighborhoods.h#L769) | Return type: `bool ` \u003cbr /\u003e |"]]
