weka.classifiers.trees.adtree.ReferenceInstances.addReference()
Adds one instance reference to the end of the set. Does not copy instance before it is added. Increases the size of the dataset if it is not large enough. Does not check if the instance is compatible with the dataset. @param instance the instance to be added

    public Instances instancesDownBranch(int branch, Instances instances) {
      ReferenceInstances filteredInstances = new ReferenceInstances(instances, 1);
      if (branch == -1) {
  for (Enumeration e = instances.enumerateInstances(); e.hasMoreElements(); ) {
    Instance inst = (Instance) e.nextElement();
    if (inst.isMissing(attIndex)) filteredInstances.addReference(inst);
  }
      } else if (branch == 0) {
  for (Enumeration e = instances.enumerateInstances(); e.hasMoreElements(); ) {
    Instance inst = (Instance) e.nextElement();
    if (!inst.isMissing(attIndex) && inst.value(attIndex) == trueSplitValue)
