# 简介

C风格的图构建器结构体，C、C++的内部实现类，C用户构图调用esb_funcs.h接口即可，C++用户调用EsGraphBuilder类的对外接口即可。

#### 需要包含的头文件

```
#include <es_c_graph_builder.h>
```


#### Public成员函数

```
EsCGraphBuilder()
explicit EsCGraphBuilder(const char *name)
~EsCGraphBuilder()
EsCGraphBuilder(EsCGraphBuilder &&) noexcept
EsCGraphBuilder &operator=(EsCGraphBuilder &&) noexcept
EsCTensorHolder *GetTensorHolderFromNode(const ge::GNode &node, int32_t output_index)

ge::Graph *GetGraph()
