Method Summary

Modifier and Type	Method	Description
void	solvingEnded(SolverScope<Solution_> solverScope)
default void	solvingError(SolverScope<Solution_> solverScope, Exception exception)	Invoked in case of an exception in the Solver run.
void	solvingStarted(SolverScope<Solution_> solverScope)

Method Details

solvingStarted

void solvingStarted(SolverScope<Solution_> solverScope)

solvingEnded

void solvingEnded(SolverScope<Solution_> solverScope)

solvingError

default void solvingError(SolverScope<Solution_> solverScope,
 Exception exception)

Invoked in case of an exception in the Solver run. In that case, the solvingEnded(SolverScope) is never called. For internal purposes only.
