Method Detail

getPhaseTypeString

public String getPhaseTypeString()

Specified by:

getPhaseTypeString in class AbstractPhase<Solution_>

solve

public void solve(SolverScope<Solution_> solverScope)

Specified by:

solve in interface Phase<Solution_>

solvingStarted

public void solvingStarted(SolverScope<Solution_> solverScope)

Specified by:

solvingStarted in interface SolverLifecycleListener<Solution_>

Overrides:

solvingStarted in class AbstractPhase<Solution_>

phaseStarted

public void phaseStarted(ConstructionHeuristicPhaseScope<Solution_> phaseScope)

stepStarted

public void stepStarted(ConstructionHeuristicStepScope<Solution_> stepScope)

stepEnded

public void stepEnded(ConstructionHeuristicStepScope<Solution_> stepScope)

phaseEnded

solvingError

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

Description copied from interface: SolverLifecycleListener

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

Specified by:

solvingError in interface SolverLifecycleListener<Solution_>
