Interface SolverJob<Solution_,ProblemId_>

Type Parameters:

Solution_ - the solution type, the class with the PlanningSolution annotation

ProblemId_ - the ID type of a submitted problem, such as Long or UUID.

All Known Implementing Classes:

DefaultSolverJob

public interface SolverJob<Solution_,ProblemId_>

Represents a problem that has been submitted to solve on the SolverManager.

Method Summary

Modifier and Type	Method and Description
Solution_	getFinalBestSolution() Waits if necessary for the solver to complete and then returns the final best PlanningSolution.
ProblemId_	getProblemId()
SolverStatus	getSolverStatus() Returns whether the Solver is scheduled to solve, actively solving or not.
void	terminateEarly() Terminates the solver or cancels the solver job if it hasn't (re)started yet.

Method Detail

getProblemId

ProblemId_ getProblemId()

Returns:

never null, a value given to SolverManager.solve(Object, Function, Consumer) or SolverManager.solveAndListen(Object, Function, Consumer)

getSolverStatus

SolverStatus getSolverStatus()

Returns whether the Solver is scheduled to solve, actively solving or not.

Returns SolverStatus.NOT_SOLVING if the solver already terminated.

Returns:

never null

terminateEarly

void terminateEarly()

Terminates the solver or cancels the solver job if it hasn't (re)started yet.

Does nothing if the solver already terminated.

Waits for the termination or cancellation to complete before returning. During termination, a bestSolutionConsumer could still be called (on a consumer thread), before this method returns.

getFinalBestSolution

Solution_ getFinalBestSolution()
                        throws InterruptedException,
                               ExecutionException

Waits if necessary for the solver to complete and then returns the final best PlanningSolution.

Returns:

never null, but it could be the original uninitialized problem

Throws:

InterruptedException - if the current thread was interrupted while waiting

ExecutionException - if the computation threw an exception
