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));
}
}示例3: _outlet
function _outlet(changes: any[]): string {
if (!isString(changes[0])) return null;
let parts = changes[0].toString().split(":");
return parts.length > 1 ? parts[0] : null;
}示例4: _segment
function _segment(changes: any[]): any {
if (!isString(changes[0])) return changes[0];
let parts = changes[0].toString().split(":");
return parts.length > 1 ? parts[1] : changes[0];
