# 简介

ContextBuilder类提供一系列的API接口，支持手动构造TilingContext(https://www.hiascend.comdocument/detail/zh/canncommercial/900/maintenref/basicdataapi/atlasopapi_07_00223.html)类来验证Tiling函数以及KernelContext类用于TilingParse函数的验证。

#### 调用示例

```
// 构造KernelContext
auto kernelContextHolder = context_ascendc::ContextBuilder()
    .Inputs(...)
    .Outputs(...)
    .BuildKernelRunContext();
gert::KernelContext* tilingParseContext = kernelContextHolder->GetContext<gert::KernelContext>();

// 构造TilingContext
auto tilingContextHolder = context_ascendc::ContextBuilder()
    .SetOpNameType(...,...)
    .NodeIoNum(...)
    .IrInstanceNum(...)
    .AddInputTd(...)
    .AddOutputTd(...)
    .AddAttr(...)
    .BuildTilingContext(...);
gert::TilingContext* tilingContext = tilingContextHolder->GetContext<gert::TilingContext>();
```
