LSCallback Interface

class 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 1: When a callback is called, the solver is paused. In that state, you can call all the methods marked as “allowed in state S_Paused. Calling any other method will throw an error.

Note 2: LocalSolver does not manage memory of objects created outside of its environment. Thus, you have to explicitly remove and delete your LSCallback at the end of the search.
