Constructor Details

EvaluationService

public EvaluationService(IExecutionService executionService,
 IEvaluationStrategy evaluationStrategy)

Creates an instance of EvaluationService.

Parameters:

executionService - execution service for creating the underlying executions to be evaluated

evaluationStrategy - evaluation strategy to use for evaluation

Throws:

IllegalArgumentException - if executionService is null or if evaluationStrategy is null

Method Details

evaluateSolutionOnAllProblemCases

public boolean evaluateSolutionOnAllProblemCases(Program solution,
 Problem problem)

Description copied from interface: IEvaluationService

Evaluates player's solution program against all of the problem cases of the given problem.

Specified by:

evaluateSolutionOnAllProblemCases in interface IEvaluationService

Parameters:

solution - solution program to evaluate

problem - problem to evaluate against

Returns:

true if the solution has passed all the problems cases, else false

getEvaluatorForProblemCaseSolution

public ISolutionEvaluator getEvaluatorForProblemCaseSolution(Program solution,
 ProblemCase problemCase)

Description copied from interface: IEvaluationService

Provides an evalutor for the solution program against the given specific problem case. This approach is recommended when the state of the underlying execution needs to be observed during the evaluation.

Specified by:

getEvaluatorForProblemCaseSolution in interface IEvaluationService

Parameters:

solution - solution program to evaluate

problemCase - problem case to evaluate against

Returns:

evaluator for the given problem case
