LSCallback (LocalSolver 12.5 API)

```
public interface LSCallback
```
LSCallback interface. Implementing the LSCallback interface enables users to call functions to react to specific events or to call a function regularly during the search. It can be used for example to control when to stop the search or to display some specific information during the search.
Note: When a callback is called, the solver is paused. In that state, you can call all the methods marked as "allowed in state LSState.Paused". Calling any other method will throw an error.
