|
|
void AddRef();
|

```
|

|

|

|
|
增加引用计数。
|

|
**描述**
|
|||
|
|
|
|||
|
|
原子地增加引用计数。在复制 `RefCounted` 指针或传递引用时调用此方法。
|
|||
|
|
|
|||
|

**复杂度：** O(1)

**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
#include <XCEngine/Core/RefCounted.h>
|
|||
|
|
|
|||
|
|
class MyObject : public RefCounted {
|
|||
|
|
public:
|
|||
|
|
void DoSomething() { /* ... */ }
|
|||
|
|
};
|
|||
|
|
|
|||
|
|
// 创建对象（构造时 refCount = 1）
|
|||
|
|
MyObject* obj = new MyObject();
|
|||
|
|
|
|||
|
|
// 手动增加引用
|
|||
|
|
obj->AddRef(); // refCount = 2
|
|||
|
|
obj->AddRef(); // refCount = 3
|
|||
|
|
|
|||
|
|
// 需要释放额外的引用
|
|||
|
|
obj->Release(); // refCount = 2
|
|||
|
|
obj->Release(); // refCount = 1
|
|||
|
|
```
