查看源码：容器中 beforeResolving() 是在哪里调用的

    /**
     * Register a new before resolving callback for all types.
     *
     * @param  \Closure|string  $abstract
     * @param  \Closure|null  $callback
     * @return void
     */
    public function beforeResolving($abstract, Closure $callback = null)
    {
        if (is_string($abstract)) {
            $abstract = $this->getAlias($abstract);
        }

        if ($abstract instanceof Closure && is_null($callback)) {
            $this->globalBeforeResolvingCallbacks[] = $abstract;
        } else {
            $this->beforeResolvingCallbacks[$abstract][] = $callback;
        }
    }

查看源码发现 $this->globalBeforeResolvingCallbacks的值是通过 beforeResolving（）函数添加的，但是没有找到 beforeResolving（）函数是在哪里被调用呢？

求指导！
