Constructor Details

SolutionEvaluator

public SolutionEvaluator(IExecutionContext executionContext,
 IEvaluationStrategy evaluationStrategy,
 ProblemCase problemCase)

Creates an instance of SolutionEvaluator.

Parameters:

executionContext - execution context to evaluate

evaluationStrategy - evaluation strategy to use for evaluation

problemCase - problem case to evaluate against

Throws:

IllegalArgumentException - if any parameter is null

Method Details

hasFinished

public boolean hasFinished()

Description copied from interface: ISolutionEvaluator

Checks if the evaluator has finished its evaluation.

Specified by:

hasFinished in interface ISolutionEvaluator

Returns:

true if evaluator has finished, else false

isSuccessful

public boolean isSuccessful()

Description copied from interface: ISolutionEvaluator

Checks if the evaluation of the execution context is successful. Result of this method should only be considered if the evaluator has finished its evaluation.

Specified by:

isSuccessful in interface ISolutionEvaluator

Returns:

true if the evaluation has ended and is successful, else false

getExecutionContext

public IExecutionContext getExecutionContext()

Description copied from interface: ISolutionEvaluator

Returns the execution context that is being evaluated by the evaluator.

Specified by:

getExecutionContext in interface ISolutionEvaluator

Returns:

evaluated execution context

step

public void step()

Description copied from interface: ISolutionEvaluator

Steps the underlying execution and checks if the new state satisfies the rules being evaluated. If the underlying execution throws an exception, the evaluation is considered finished as a failure and the StepEvaluationException is thrown with the details of the failure.

Specified by:

step in interface ISolutionEvaluator
