示例1: link

export function link(segment: RouteSegment, routeTree: RouteTree, urlTree: UrlTree,
                     change: any[]): UrlTree {
  if (change.length === 0) return urlTree;

  let startingNode;
  let normalizedChange;

  if (isString(change[0]) && change[0].startsWith("./")) {
    normalizedChange = ["/", change[0].substring(2)].concat(change.slice(1));
    startingNode = _findStartingNode(_findUrlSegment(segment, routeTree), rootNode(urlTree));

  } else if (isString(change[0]) && change.length === 1 && change[0] == "/") {
    normalizedChange = change;
    startingNode = rootNode(urlTree);

  } else if (isString(change[0]) && !change[0].startsWith("/")) {
    normalizedChange = ["/"].concat(change);
    startingNode = _findStartingNode(_findUrlSegment(segment, routeTree), rootNode(urlTree));

  } else {
    normalizedChange = ["/"].concat(change);
    startingNode = rootNode(urlTree);
  }

  let updated = _update(startingNode, normalizedChange);
  let newRoot = _constructNewTree(rootNode(urlTree), startingNode, updated);

  return new UrlTree(newRoot);
}

示例2: _update

function _update(node: TreeNode<UrlSegment>, changes: any[]): TreeNode<UrlSegment> {
  let rest = changes.slice(1);
  let outlet = _outlet(changes);
  let segment = _segment(changes);
  if (isString(segment) && segment[0] == "/") segment = segment.substring(1);

  // reach the end of the tree => create new tree nodes.
  if (isBlank(node)) {
    let urlSegment = new UrlSegment(segment, null, outlet);
    let children = rest.length === 0 ? [] : [_update(null, rest)];
    return new TreeNode<UrlSegment>(urlSegment, children);

    // different outlet => preserve the subtree
  } else if (outlet != node.value.outlet) {
    return node;

    // same outlet => modify the subtree
  } else {
    let urlSegment = isStringMap(segment) ? new UrlSegment(null, segment, null) :
                                            new UrlSegment(segment, null, outlet);
    if (rest.length === 0) {
      return new TreeNode<UrlSegment>(urlSegment, []);
    }

    return new TreeNode<UrlSegment>(urlSegment,
                                    _updateMany(ListWrapper.clone(node.children), rest));
  }
}
