# LinearAllocator::GetPeakAllocated
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
size_t GetPeakAllocated() const override;
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
返回自分配器创建以来的峰值分配字节数。对于线性分配器，这等于总容量（`m_capacity`）。
|
|||
|
|
|
|||
|
|
**参数：** 无
|
|||
|
|
|
|||
|
|
**返回：** 峰值分配字节数（等于容量）
|
|||
|
|
|
|||
|
|
**复杂度：** O(1)
|
|||
|
|
|

|
|
**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
#include <XCEngine/Memory/LinearAllocator.h>
|
|||
|
|
|
|||
|
|
LinearAllocator allocator(1024);
|
|||
|
|
|
|||
|
|
size_t peak = allocator.GetPeakAllocated(); // 1024（容量）
|
|||
|
|
|
|||
|
|
allocator.Allocate(512);
|
|||
|
|
size_t used = allocator.GetUsedSize(); // 512
|
|||
|
|
|
|||
|
|
// 即使未达到容量，峰值仍为容量大小
|
|||
|
|
size_t peak_after = allocator.GetPeakAllocated(); // 1024
|
|||
|
|
```
