# LinearAllocator::GetTotalFreed
|
|
|
|
```cpp
|
|
size_t GetTotalFreed() const override;
|
|
```
|
|
|
|
返回自分配器创建以来的累计释放字节数。线性分配器不支持单个块释放，始终返回 0。
|
|
|
|
**参数：** 无
|
|
|
|
**返回：** 始终返回 `0`
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include <XCEngine/Memory/LinearAllocator.h>
|
|
|
|
LinearAllocator allocator(1024);
|
|
|
|
void* ptr = allocator.Allocate(256);
|
|
allocator.Free(ptr); // 无实际效果
|
|
|
|
size_t freed = allocator.GetTotalFreed(); // 0
|
|
```
