# RefCounted::GetRefCount

```cpp
uint32_t GetRefCount() const;
```

获取当前引用计数。

**描述**

返回当前的引用计数值。由于使用 `std::atomic` 实现，因此是线程安全的。

**返回：** `uint32_t` - 当前引用计数

**线程安全：** ✅

**复杂度：** O(1)

**示例：**

```cpp
#include <XCEngine/Core/RefCounted.h>
#include <cstdio>

class MyObject : public XCEngine::Core::RefCounted {
public:
    void Debug() {
        printf("RefCount: %u\n", GetRefCount());
    }
};

int main() {
    MyObject* obj = new MyObject();
    printf("After create: %u\n", obj->GetRefCount());
    
    obj->AddRef();
    printf("After AddRef: %u\n", obj->GetRefCount());
    
    obj->Release();
    printf("After Release: %u\n", obj->GetRefCount());
    
    obj->Release();
    return 0;
}
```
