Class Evaluator.AsPathEvaluator<STATE>
java.lang.Object
org.neo4j.graphdb.traversal.Evaluator.AsPathEvaluator<STATE>
- Type Parameters:
STATE - the type of state passed into the evaluator.
- All Implemented Interfaces:
- Evaluator, PathEvaluator<STATE>
- Enclosing interface:
- Evaluator
public static class Evaluator.AsPathEvaluator<STATE>
- extends Object
- implements PathEvaluator<STATE>
Exposes an Evaluator as a PathEvaluator.
Evaluator.AsPathEvaluator
public Evaluator.AsPathEvaluator(Evaluator evaluator)
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.
