# Parse GS1 AI

## How to Enable GS1 AI Parsing

1. Add code parser task.

   ```json
   "CodeParserTaskSettingOptions": [
     {
       "Name": "parse_gs1",
       "CodeSpecifications": [
         "GS1_AI"
       ]
     }
   ]
   ```

2. Add semantic processing options and specify the target ROI to reference.

   ```json
   "SemanticProcessingOptions": [
     {
       "Name": "sp_gs1",
       "ReferenceObjectFilter": {
         "ReferenceTargetROIDefNameArray": [
           "roi_read_gs1"
         ]
       },
       "TaskSettingNameArray": [
         "parse_gs1"
       ]
     }
   ]
   ```

3. Add the semantic processing option names to your template.

   ```json
   "CaptureVisionTemplates": [
     {
       "Name": "ReadGS1AI",
       "ImageROIProcessingNameArray": [
         "roi_read_gs1"
       ],
       "SemanticProcessingNameArray": [
         "sp_gs1"
       ]
     }
   ]
   ```

## How to Receive Parsed Results

Receive the `ParsedResult` from the [`onParsedResultsReceived`]({{ site.dcvb_android_api }}capture-vision-router/auxiliary-classes/captured-result-receiver.html) callback of `CapturedResultReceiver`.

<div class="sample-code-prefix"></div>
>- Java
>- Kotlin
>
>1. 
```java
mRouter.addResultReceiver(new CapturedResultReceiver() {
   @Override
   public void onParsedResultsReceived(@NonNull ParsedResult result) {
          // Add your code to use the ParsedResult
   }
});
```
2. 
```kotlin
cvr.addResultReceiver(object: CapturedResultReceiver{
   override fun onParsedResultsReceived(result: ParsedResult) {
          // Add your code to use the ParsedResult
   }
})
```

You can also receive the `ParsedResult` from the [`onCapturedResultReceived`]({{ site.dcvb_android_api }}capture-vision-router/auxiliary-classes/captured-result-receiver.html) callback if you want to use the barcode result as well.

<div class="sample-code-prefix"></div>
>- Java
>- Kotlin

>1. 
```java
mRouter.addResultReceiver(new CapturedResultReceiver() {
   @Override
   public void onCapturedResultReceived(@NonNull CapturedResult result) {
          DecodedBarcodesResult decodedBarcodesResult = result.getDecodedBarcodesResult();
          ParsedResult parsedResult = result.getParsedResult();
   }
});
```
2. 
```kotlin
cvr.addResultReceiver(object: CapturedResultReceiver{
   override fun onCapturedResultReceived(result: CapturedResult) {
          val parsedResult = result.parsedResult
          val decodedBarcodesResult = result.decodedBarcodesResult
   }
})
```
