public AsPathEvaluator(Evaluator evaluator)

Method Details

evaluate

public Evaluation evaluate(Path path,
 BranchState<STATE> state)

Description copied from interface: PathEvaluator

Evaluates a Path and returns an Evaluation containing information about whether or not to include it in the traversal result, i.e return it from the Traverser. And also whether or not to continue traversing down that path or if it instead should be pruned so that the traverser won't continue down that branch represented by path.

Specified by:

evaluate in interface PathEvaluator<STATE>

Parameters:

path - the Path to evaluate.

state - the state of this branch in the current traversal.

Returns:

an Evaluation containing information about whether or not to return it from the Traverser and whether or not to continue down that path.

evaluate

public Evaluation evaluate(Path path)

Description copied from interface: Evaluator

Evaluates a Path and returns an Evaluation containing information about whether or not to include it in the traversal result, i.e return it from the Traverser. And also whether or not to continue traversing down that path or if it instead should be pruned so that the traverser won't continue down that branch represented by path.

Specified by:

evaluate in interface Evaluator

Parameters:

path - the Path to evaluate.

Returns:

an Evaluation containing information about whether or not to return it from the Traverser and whether or not to continue down that path.
