# ProxyAllocator::Free
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
void Free(void* ptr) override;
|
||
|
|
```
|
||
|
|
|
||
|
|
释放内存并记录统计。调用转发到底层分配器，同时更新统计信息：增加总释放计数（而非字节大小，因为 ProxyAllocator 不记录释放的字节数），并递减当前分配计数。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `ptr` - 指向要释放的内存块
|
||
|
|
|
||
|
|
**返回：** 无
|
||
|
|
|
||
|
|
**复杂度：** O(1)（底层释放 + 统计更新）
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#include <XCEngine/Memory/MemoryManager.h>
|
||
|
|
#include <XCEngine/Memory/ProxyAllocator.h>
|
||
|
|
|
||
|
|
IAllocator* sysAlloc = MemoryManager::Get().GetSystemAllocator();
|
||
|
|
ProxyAllocator proxy(sysAlloc, "TrackedAlloc");
|
||
|
|
|
||
|
|
void* p1 = proxy.Allocate(512);
|
||
|
|
void* p2 = proxy.Allocate(256);
|
||
|
|
|
||
|
|
proxy.Free(p1);
|
||
|
|
proxy.Free(p2);
|
||
|
|
|
||
|
|
const auto& stats = proxy.GetStats();
|
||
|
|
printf("Total allocated: %zu, Total freed: %zu, Current: %zu\n",
|
||
|
|
stats.totalAllocated, stats.totalFreed,
|
||
|
|
stats.totalAllocated - stats.totalFreed);
|
||
|
|
```
