# RefCounted::Release
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
void Release();
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
减少引用计数。
|
|||
|
|
|
|||
|
|
**描述**
|
|||
|
|
|
|||
|
|
原子地减少引用计数。当引用计数归零时，对象会自动 `delete this`。这是实现自动内存管理的关键方法。
|
|||
|
|
|
|||
|
|
**复杂度：** O(1)（归零时为 O(n)，n 为对象大小）
|
|||
|
|
|
|||
|
|
**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
|
|||
|
|
|
|||
|
|
// 释放引用
|
|||
|
|
obj->Release(); // refCount = 1
|
|||
|
|
obj->Release(); // refCount = 0, 对象被自动 delete
|
|||
|
|
```
