# LinearAllocator::Free
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
void Free(void* ptr) override;
|
||
|
|
```
|
||
|
|
|
||
|
|
此方法对 LinearAllocator 无实际效果。线性分配器不支持单个内存块的释放，因为内存是顺序分配的，释放中间某块会破坏后续分配的完整性。需要释放所有内存时使用 `Clear()` 方法。
|

|
|
|
||
|
|
**参数：**
|
||
|
|
- `ptr` - 被忽略
|
||
|
|
|
||
|
|
**返回：** 无
|
||
|
|
|
||
|
|
**复杂度：** O(1)（空操作）
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#include <XCEngine/Memory/LinearAllocator.h>
|
||
|
|
|
||
|
|
LinearAllocator allocator(1024);
|
||
|
|
void* ptr = allocator.Allocate(256);
|
||
|
|
void* ptr2 = allocator.Allocate(128);
|
||
|
|
|
||
|
|
// Free 实际上什么都不做
|
||
|
|
allocator.Free(ptr);
|
||
|
|
allocator.Free(ptr2);
|
||
|
|
|
||
|
|
// 如需释放所有内存，应使用 Clear
|
||
|
|
allocator.Clear();
|
||
|
|
```
