示例1: constructor
constructor(bindingEngine: BindingEngine){
this.name = 'Vlad';
let subscription = bindingEngine
.propertyObserver(this, 'name')
.subscribe(this.nameChange);
}示例2: recurse
private recurse(target, property, subscriptions, callback, path) {
let sub = target[property];
if (typeof sub === "object") {
for (var p in sub)
if (sub.hasOwnProperty(p)) {
this.recurse(sub, p, subscriptions, callback, `${path}${sub instanceof Array ? '[' + p + ']' : '.' + p}`);
}
}
if (target != property) // Avoid re-observice root node
{
subscriptions.push(this._bindingEngine.propertyObserver(target, property).subscribe((n, o) => callback(n, o, path)));
}
};示例3: observe
public observe(target: Object, property: string, callback: (n: any, o: any, name: string) => void): () => void {
var subscriptions: { root: any, children: any[] } = { root: null, children: [] };
subscriptions.root = (this._bindingEngine.propertyObserver(target, property)
.subscribe((n, o) => {
