### Question:
NodeConverter implements NodeToRelatedTreeConverter<E, MutableSettableStructuredNode<E>,
    LinkedTree<E>> { @Override public Class<? extends OpenNode> forClass() { return LinkedTree.class; }  @Override LinkedTree<E> treeFromRootNode(MutableSettableStructuredNode<E> node); @Override Class<? extends OpenNode> forClass();  }### Answer:
@Test public void forClass() { final NodeConverter<String> converter = new NodeConverter<>(); assertEquals(LinkedTree.class, converter.forClass()); }
