- org.intel.openvino.Wrapper
- - org.intel.openvino.PrePostProcessor

```
public class PrePostProcessor
extends Wrapper
```
Main class for adding pre- and post- processing steps to existing Model
This is a helper class for writing easy pre- and post- processing operations on Model object assuming that any preprocess operation takes one input and produces one output.
For advanced preprocessing scenarios, like combining several functions with multiple inputs/outputs into one, client's code can use transformation passes over Model

- Method Detail
  - input
```
public InputInfo input()
```
    Gets input pre-processing data structure. Should be used only if model/function has only one input Using returned structure application's code is able to set user's tensor data (e.g layout), preprocess steps, target model's data
    
    Returns:
    
    Reference to model's input information structure
  - output
```
public OutputInfo output()
```
    Gets output post-processing data structure. Should be used only if model/function has only one output Using returned structure application's code is able to set model's output data, post-process steps, user's tensor data (e.g layout)
    
    Returns:
    
    Reference to model's output information structure
  - build
```
public Model build()
```
    Adds pre/post-processing operations to function passed in constructor
    
    Returns:
    
    Function with added pre/post-processing operations
  - delete
```
protected void delete(long nativeObj)
```
