- com.google.ortools.sat.SolutionCallback
- - com.google.ortools.sat.CpSolverSolutionCallback

```
public class CpSolverSolutionCallback
extends SolutionCallback
```
Parent class to create a callback called at each solution.
From the parent class, it inherits the methods:
long numBooleans() to query the number of boolean variables created.
long numBranches() to query the number of branches explored so far.
long numConflicts() to query the number of conflicts created so far.
long numBinaryPropagations() to query the number of boolean propagations in the SAT solver so far.
long numIntegerPropagations() to query the number of integer propagations in the SAT solver so far.
double wallTime() to query wall time passed in the search so far.
double userTime() to query the user time passed in the search so far.
long objectiveValue() to get the best objective value found so far.
