RefCounted::GetRefCount

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:

#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
