+### Structs
+
+| Name | Description | 
+| -------- | -------- |
+| [OH_AI_TensorHandleArray](_o_h___a_i___tensor_handle_array.md) | Defines the tensor array structure, which is used to store the tensor array pointer and tensor array length.  | 
+| [OH_AI_ShapeInfo](_o_h___a_i___shape_info.md) | Defines dimension information. The maximum dimension is set by **MS_MAX_SHAPE_NUM**. | 
+| [OH_AI_CallBackParam](_o_h___a_i___call_back_param.md) | Defines the operator information passed in a callback.  | 
+
