# D3D12CommandAllocator::GetCommandAllocator

```cpp
ID3D12CommandAllocator* GetCommandAllocator() const { return m_commandAllocator.Get(); }
```

获取底层的 D3D12 命令分配器接口。

## 示例

```cpp
D3D12CommandAllocator allocator;
if (allocator.Initialize(device)) {
    ID3D12CommandAllocator* native = allocator.GetCommandAllocator();
    // 使用原生 D3D12 接口
}
```

**返回：** `ID3D12CommandAllocator*`

**复杂度：** O(1)
