# 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
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#include <XCEngine/Core/RefCounted.h>
|
||
|
|
|
||
|
|
class MyObject : public RefCounted {
|
||
|
|
public:
|
||
|
|
void Debug() {
|
||
|
|
printf("RefCount: %u\n", GetRefCount());
|
||
|
|
}
|
||
|
|
};
|
||
|
|
|
||
|
|
MyObject* obj = new MyObject();
|
||
|
|
printf("After create: %u\n", obj->GetRefCount()); // 1
|
||
|
|
|
||
|
|
obj->AddRef();
|
||
|
|
printf("After AddRef: %u\n", obj->GetRefCount()); // 2
|
||
|
|
|
||
|
|
obj->Release();
|
||
|
|
printf("After Release: %u\n", obj->GetRefCount()); // 1
|
||
|
|
```
