All Implemented Interfaces:
```
public final class CheckRecognizerFrameHandler
extends FrameHandler
                    
```
Performs check data detection on camera preview frames. Outputs results via CheckRecognizerFrameHandler.ResultHandler (.addResultHandler).
Preview frame considered intercepted if at least one CheckRecognizerFrameHandler.ResultHandler returns true from CheckRecognizerFrameHandler.ResultHandler.handle (FrameHandlerResult)}

```
@Synchronized() Boolean handleFrame(FrameHandler.Frame previewFrame)
```
    Invoked for every new camera preview frame.
    
    Parameters:
    
    previewFrame - captured preview frame data
  - addResultHandler
```
 final Unit addResultHandler(CheckRecognizerFrameHandler.ResultHandler handler)
```
    Registers result handler which will be notified about check data detection results.
    Results are coming on the worker thread. Don't forget to move execution to main thread before updating UI.
    
    Parameters:
    
    handler - handler to register.
  - removeResultHandler

 final Unit removeResultHandler(CheckRecognizerFrameHandler.ResultHandler handler)
```
    Unregisters handler.
    
    Parameters:
    
    handler - handler to unregister.
  - setReturnFrameOnSuccess
```
 final Unit setReturnFrameOnSuccess(Boolean returnFrameOnSuccess)
```
    Returns the frame in the recognition result on success.
    
    Parameters:
    
    returnFrameOnSuccess - if true camera frame will be returned in the recognition result, false - otherwise The default value is FALSE.
  - attach
```
 final static CheckRecognizerFrameHandler attach(IScanbotCameraView cameraView, CheckRecognizer checkRecognizer)
```
    Convenience method for creating new CheckRecognizerFrameHandler and adding it as FrameHandler to given camera view.
    
    Parameters:
    
    cameraView - camera view to which new check data detector will be attached
