쿼리 힙을 관리합니다. 쿼리 힙은 인덱스로 참조되는 쿼리 배열을 보유합니다.

## 설명

자세한 내용은 [쿼리](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/queries)를 참조하세요.

#### 예제

[D3D12PredicationQueries](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/working-samples) 샘플은 다음과 같이 **ID3D12QueryHeap**을 사용합니다:

쿼리 힙과 쿼리 결과 버퍼를 만듭니다.

```cpp theme={null}
// Pipeline objects.
D3D12_VIEWPORT m_viewport;
D3D12_RECT m_scissorRect;
ComPtr<IDXGISwapChain3> m_swapChain;
ComPtr<ID3D12Device> m_device;
ComPtr<ID3D12Resource> m_renderTargets[FrameCount];
ComPtr<ID3D12CommandAllocator> m_commandAllocators[FrameCount];
ComPtr<ID3D12CommandQueue> m_commandQueue;
ComPtr<ID3D12RootSignature> m_rootSignature;
ComPtr<ID3D12DescriptorHeap> m_rtvHeap;
ComPtr<ID3D12DescriptorHeap> m_cbvHeap;
ComPtr<ID3D12DescriptorHeap> m_dsvHeap;
ComPtr<ID3D12QueryHeap> m_queryHeap;
UINT m_rtvDescriptorSize;
UINT m_cbvSrvDescriptorSize;
UINT m_frameIndex;

// Synchronization objects.
ComPtr<ID3D12Fence> m_fence;
UINT64 m_fenceValues[FrameCount];
HANDLE m_fenceEvent;

// Asset objects.
ComPtr<ID3D12PipelineState> m_pipelineState;
ComPtr<ID3D12PipelineState> m_queryState;
ComPtr<ID3D12GraphicsCommandList> m_commandList;
ComPtr<ID3D12Resource> m_vertexBuffer;
ComPtr<ID3D12Resource> m_constantBuffer;
ComPtr<ID3D12Resource> m_depthStencil;
ComPtr<ID3D12Resource> m_queryResult;
D3D12_VERTEX_BUFFER_VIEW m_vertexBufferView;

```

```cpp theme={null}
// Describe and create a heap for occlusion queries.
D3D12_QUERY_HEAP_DESC queryHeapDesc = {};
queryHeapDesc.Count = 1;
queryHeapDesc.Type = D3D12_QUERY_HEAP_TYPE_OCCLUSION;
ThrowIfFailed(m_device->CreateQueryHeap(&queryHeapDesc, IID_PPV_ARGS(&m_queryHeap)));

```
