在此命名空间中,我导出一个字符串类型的Rx主题:
public IEnumerable<SiloNode> GetLinks(IEnumerable<SiloNode> masterList)
{
foreach(var node in masterList)
{
yield return node;
foreach(var children in GetLinks(node.Children))
yield return children;
}
}
在WITH RECURSIVE employee_paths AS
( SELECT employeeNumber,
reportsTo managerNumber,
officeCode,
1 lvl
FROM employees
WHERE reportsTo IS NULL
UNION ALL
SELECT e.employeeNumber,
e.reportsTo,
e.officeCode,
lvl+1
FROM employees e
INNER JOIN employee_paths ep
ON ep.employeeNumber = e.reportsTo )
SELECT employeeNumber,
managerNumber,
lvl,
city
FROM employee_paths ep
INNER JOIN offices o USING (officeCode)
ORDER BY lvl, city;
名称空间中的namespace something.TaskHandling {
export const taskSelected$ = new Rx.Subject<String>();
类中,我有:
TaskListComponent
然后在something.TaskHandling.Overview
命名空间的public clickListItem() {
taskSelected$.onNext('responsive-view-filters');
}
中导入主题:
ResponsiveNavigationComponent
我在something.CustomerService
中启动流:
import taskSelected$ = something.TaskHandling.taskSelected$;
此代码编译没有问题,当我OnInit
public $onInit() {
this.observeTaskUpdates();
}
private observeTaskUpdates(): void {
taskSelected$
.filter(classValue => !!classValue)
.subscribe(classValue => {
this.toggleView(classValue);
});
}
时,我最终遇到了导出的go to definition
主题。
但是当我运行该应用程序时,我在ResponsiveNavigationComponent.ts中得到了它:
TypeError:无法读取未定义的属性“ filter”
因此taskSelected
没有在我的taskSelected$
类中定义。我想念什么?
答案 0 :(得分:0)
这不是订单问题,我不得不硬引用启动taskSelected$
const的实际文件> /// <reference path="../TaskHandling/module.ts"/>
。不确定这是否是解决潜在问题的方法。
