public interface IBarcodeGenerator
```

Public interface for barcode custom generator. Implementation should be provided by user.

 **Remarks:** 

Generator instance should be passed through the [FieldOptions.getBarcodeGenerator()](../../com.aspose.words/fieldoptions/\#getBarcodeGenerator) / [FieldOptions.setBarcodeGenerator(com.aspose.words.IBarcodeGenerator)](../../com.aspose.words/fieldoptions/\#setBarcodeGenerator-com.aspose.words.IBarcodeGenerator) property.
