**命名空间**: `XCEngine::Core`

|
|
|
|||
|
|
**类型**: `class`

|
|
|
|||
|
|
**描述**: 引用计数基类，提供线程安全的引用计数生命周期管理。

|
## 概述
|
|||
|
|
|
|||
|
|
`RefCounted` 是一个简单的引用计数基类。当引用计数归零时，对象会自动删除。它提供了 `AddRef` 和 `Release` 方法，线程安全地管理引用计数。

## 公共方法

|
|

|
|
| 方法 | 描述 |
|
|||
|
|
|------|------|
|
|||
|
|
| `RefCounted()` | 构造函数，初始引用计数为 1 |
|
|||
|
|
| `virtual ~RefCounted()` | 虚析构函数 |
|
|||
|
|
| [`AddRef`](AddRef.md) | 增加引用计数 |
|
|||
|
|
| [`Release`](Release.md) | 减少引用计数（归零时自动 delete this） |
|
|||
|
|
| [`GetRefCount`](GetRefCount.md) | 获取当前引用计数 |
|
|||
|
|
|
|||
|
|
## 使用示例
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
class MyObject : public RefCounted {
|
|||
|
|
public:
|
|||
|
|
MyObject() { /* ... */ }
|
|||
|
|
~MyObject() { /* ... */ }
|
|||
|
|
|
|||
|
|
void DoSomething() { /* ... */ }
|
|||
|
|
};
|
|||
|
|
|
|||
|
|
// 使用
|
|||
|
|
MyObject* obj = new MyObject(); // refCount = 1
|
|||
|
|
obj->AddRef(); // refCount = 2
|
|||
|
|
obj->Release(); // refCount = 1
|
|||
|
|
obj->Release(); // refCount = 0, 自动 delete
|
|||
|
|
```
