# 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：递增 `totalFreed`（累加当前 `allocationCount`），并递减 `allocationCount`。
|
||
|
||
**注意：** `totalFreed` 累加的是每次释放时的 `allocationCount`（分配计数）而非实际字节大小。这是一个简化的实现，用于追踪释放操作次数。
|
||
|
||
**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();
|
||
// totalFreed 累加了每次释放时的 allocationCount（次数，非字节）
|
||
// allocationCount 最终为 0
|
||
printf("Total allocated: %zu bytes, Freed count: %zu, Current count: %zu\n",
|
||
stats.totalAllocated, stats.totalFreed, stats.allocationCount);
|
||
```
