|
||
|
|
|
||
|
|
```cpp
|
||
|
|
size_t GetTotalAllocated() const override;
|
||
|
|
```
|
||
|
|
|
||
|
|
返回当前已分配的内存总量（字节）。计算公式：`(m_totalBlocks - m_freeBlocks) * m_blockSize`。
|
||
|
|
|
||
|
|
**参数：** 无
|
||
|
|
|
||
|
|
**返回：** 当前已分配块的字节数
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|

|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#include <XCEngine/Memory/PoolAllocator.h>
|
||
|
|
|
||
|
|
PoolAllocator pool(sizeof(int), 100);
|
||
|
|
|
||
|
|
size_t allocated = pool.GetTotalAllocated(); // 0
|
||
|
|
|
||
|
|
void* block = pool.Allocate();
|
||
|
|
allocated = pool.GetTotalAllocated(); // sizeof(int)
|
||
|
|
|
||
|
|
pool.Free(block);
|
||
|
|
allocated = pool.GetTotalAllocated(); // 0
|
||
|
|
```
