org.sindice.siren.index.IntervalConstrainedNodesEnum

Implementation of {@link ConstrainedNodesEnum} to apply a level constraintand a stack of interval constraints over the retrieved node labels.

This {@link ConstrainedNodesEnum} applies a stack of interval constraints.A stack of interval constraints is composed of a list of pairs (level, interval constraint), each pair indicates one interval constraint to apply on specific level of the node labels. @see NodeUtils#isConstraintSatisfied(IntsRef,int[],int[][])

    if (stack.size() > 0) {
      // add the interval constraint of the current node
      if (lowerBound != -1 && upperBound != -1) {
        stack.add(levelConstraint, lowerBound, upperBound);
      }
      return new IntervalConstrainedNodesEnum(sirenDocsEnum, levelConstraint,
        stack.getLevelIndex(), stack.getConstraints());
    }
    // if an interval constraint has been set for the current node
    else if (lowerBound != -1 && upperBound != -1) {
      // use the interval constraint of the current node
