All Implemented Interfaces:
```
public class BarcodeCounterFrameHandler
extends FrameHandler
                    
```
Performs barcode/QR code scanning on camera preview frames. Outputs results via BarcodeCounterFrameHandler.ResultHandler (addResultHandler).
Preview frame considered intercepted if at least one BarcodeCounterFrameHandler.ResultHandler returns true from BarcodeCounterFrameHandler.ResultHandler.handle

```
- Method Detail
  - getViewHandler
```
 final BarcodeCounterFrameHandler.ResultHandler getViewHandler()
```
  - setViewHandler
```
 final Unit setViewHandler(BarcodeCounterFrameHandler.ResultHandler viewHandler)
```
  - isEnabled
```
 Boolean isEnabled()
```
    Set true to enable barcode/QR code scanning. false to disable barcode/QR code scanning is disabled, i.e. incoming frames are skipped.
  - setEnabled
```
 Unit setEnabled(Boolean isEnabled)
```
    Set true to enable barcode/QR code scanning. false to disable barcode/QR code scanning is disabled, i.e. incoming frames are skipped.
  - handleFrame
```
@Synchronized() Boolean handleFrame(FrameHandler.Frame previewFrame)
```
    Invoked for every new camera preview frame.
    
    Parameters:
    
    previewFrame - captured preview frame data
  - resetViewState
```
 final Unit resetViewState()
```
    Reset subscribed view component to initial state.
  - addResultHandler
```
 final Unit addResultHandler(BarcodeCounterFrameHandler.ResultHandler handler)
```
    Registers result handler which will be notified about barcode/QR code scanning 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.
  - performSingleShotScan
```
 final Unit performSingleShotScan()
```
    Enable scanner to one time scan on Frame.
  - removeResultHandler
```
 final Unit removeResultHandler(BarcodeCounterFrameHandler.ResultHandler handler)
```
    Unregisters handler.
    
    Parameters:
    
    handler - handler to unregister.
  - setBarcodeFilter
```
 final Unit setBarcodeFilter(IBarcodeFilter filter)
```
    Set implementation of IBarcodeFilter, that will be applied to every frame after scanning and filter frames with undesired data.
    NOTE: here, for BarcodeScanner (as opposed to BatchBarcodeScanner) only IBarcodeFilter.acceptsBarcode filtering method will be used.
    
    Parameters:
    
    filter - IBarcodeFilter implementation.
  - attach
```
 final static BarcodeCounterFrameHandler attach(IScanbotCameraView cameraView, BarcodeScanner barcodeScanner)
```
    Convenience method for creating new BarcodeCounterFrameHandler and adding it as FrameHandler to given camera view.
    
    Parameters:
    
    cameraView - camera view to which new barcode/QR code scanner will be attached
    
    barcodeScanner - BarcodeScanner which performs barcode scanning
