示例1: retract
import org.apache.tinkerpop.gremlin.process.traversal.Path; //导入方法依赖的package包/类
@Override
public Path retract(final Set<String> labels) {
if (labels.isEmpty())
return this;
// get all the immutable path sections
final List<ImmutablePath> immutablePaths = new ArrayList<>();
ImmutablePath currentPathSection = this;
while (true) {
immutablePaths.add(0, currentPathSection);
if (currentPathSection.previousPath instanceof TailPath)
break;
else
currentPathSection = (ImmutablePath) currentPathSection.previousPath;
}
// build a new immutable path using the respective path sections that are not to be retracted
Path newPath = TailPath.instance();
for (final ImmutablePath immutablePath : immutablePaths) {
final Set<String> temp = new LinkedHashSet<>(immutablePath.currentLabels);
temp.removeAll(labels);
if (!temp.isEmpty())
newPath = newPath.extend(immutablePath.currentObject, temp);
}
return newPath;
