{
//child behavior
while (true) { std::cout << "child" << std::endl; sleep(1); }
}
else
{
//do s

我正在尝试开发我的第一个Drupal 8模块,我不明白为什么在我的小枝模板中没有定义jQuery。

public function build() {

然后在控制器中:
public function displaySlider($slider_id) {

我有四节课
class A { //a base class
public:
A(ostringstream* os){ oss2=os; }
ostringstream* oss2;
};
class B : public A{ // a derived class
public:
B(ostringstream* os):A(os){};
};
class C { //class where oss is actually declared
public:
C(){};
ostringstream oss;
};
最后(
我试过了:
ostringstream oss;

有人能告诉我为什么吗?谢谢。
