Angular2 - rxjs观察与处置？

Question

取消订阅和处置之间的区别是什么？

e.g。

getTodos(): Promise<Todo[]> {
    return this.http.get(this.todosUrl)
    .toPromise()
    .then(response => { return response.json() as Todo[]})

Answer 1

这是rxjs4 - rxjs5差异;

rxjs4 Disposable dispose()有Subscription个unsubscribe()，现在var cp = require( 'child_process' ); var dbWatcher; if ( !processDoesExist ) { dbWatcher = cp.fork( __dirname + '/dbWatcher.js', [], {execArgv: ['--debug=5859']} ); } else { dbWatcher.send( message ); } 为cp.fork()
