Barcode Tracking Deserializer#

Defined in framework ScanditBarcodeCapture

Warning

The deserialization API is not yet stable and will still change over the coming releases.

Note

This deserializer is not thread-safe, subsequent calls for the same settings, mode or overlay have to be called on the same thread.

SDCBarcodeTrackingDeserializer#
@interface SDCBarcodeTrackingDeserializer : NSObject <SDCDataCaptureModeDeserializer>

Added in version 6.1.0

A deserializer to construct barcode tracking from JSON. For most use cases it is enough to use SDCBarcodeTracking.barcodeTrackingFromJSONString:context:error: which internally uses this deserializer. Using the deserializer gives the advantage of being able to listen to the deserialization events as they happen and potentially influence them. Additonally warnings can be read from the deserializer that would otherwise not be available.
