# RHIBuffer::GetState

```cpp
virtual ResourceStates GetState() const = 0;
```

获取缓冲区当前所处的资源状态。资源状态决定缓冲区可以用于哪些 GPU 操作。

**返回：** `ResourceStates` 枚举值

**线程安全：** ✅

**复杂度：** O(1)

**示例：**

```cpp
ResourceStates state = buffer->GetState();
if (state == ResourceStates::VertexAndConstantBuffer) {
    printf("Buffer is ready for vertex binding\n");
}
```
