是“删除此"吗?允许在C ++中使用? [英] Is "delete this" allowed in C++?

问题描述

是否允许删除此内容>，如果delete-statement是将在该类实例上执行的最后一条语句?当然，我确定 this 指针所表示的对象是 new new创建的.

Is it allowed to delete this; if the delete-statement is the last statement that will be executed on that instance of the class? Of course I'm sure that the object represented by the this-pointer is newly-created.

我正在考虑这样的事情:

I'm thinking about something like this:

void SomeModule::doStuff()
{
    // in the controller, "this" object of SomeModule is the "current module"
    // now, if I want to switch over to a new Module, eg:

    controller->setWorkingModule(new OtherModule());

    // since the new "OtherModule" object will take the lead, 
    // I want to get rid of this "SomeModule" object:

    delete this;
}

我可以这样做吗?

推荐答案

C ++ FAQ Lite专门为此提供了一个条目

The C++ FAQ Lite has a entry specifically for this

• https://isocpp.org/wiki/faq/freestore-mgmt#删除此

我认为这句话很好地概括了

I think this quote sums it up nicely

只要小心，对象可以自杀(删除该对象).

As long as you're careful, it's OK for an object to commit suicide (delete this).
