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

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

    // Remove all annotations.
    for (int i = 0; i < fsArray.length; i++) {
      ir.removeFS(fsArray[i]);
    }
    // All iterators should be invalidated when being reset.
    bagIt.moveToFirst();
    assertFalse(bagIt.isValid());
    setIt.moveToFirst();
    assertFalse(setIt.isValid());
    sortedIt.moveToFirst();
    assertFalse(sortedIt.isValid());
