Examples of org.apache.uima.cas.FSIterator.moveToLast()

org.apache.uima.cas.FSIterator.moveToLast()
Move the iterator to the last element. The iterator will be valid iff the underlying collection is non-empty. Allowed even if the underlying indexes being iterated over were modified.

  public void moveToLast() {
    // See comments on moveToFirst()
    this.iteratorIndex = this.iterators.size() - 1;
    while (this.iteratorIndex >= 0) {
      FSIterator it = (FSIterator) this.iterators.get(this.iteratorIndex);
      it.moveToLast();
      if (it.isValid()) {
        return;
      }
      --this.iteratorIndex;
