问题描述
是否允许 delete this; 如果删除语句是将在类的该实例上执行的最后一条语句?当然，我确信 this 指针所代表的对象是 newly-created.
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 有一个专门针对此的条目
The C++ FAQ Lite has a entry specifically for this
- https://isocpp.org/wiki/faq/freestore-mgmt#删除-这个
我觉得这句话总结得很好
I think this quote sums it up nicely
只要你小心，一个对象自杀是可以的(删除这个).
As long as you're careful, it's OK for an object to commit suicide (delete this).
