Barcode Capture 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.

SDCBarcodeCaptureDeserializer#
@interface SDCBarcodeCaptureDeserializer : NSObject <SDCDataCaptureModeDeserializer>

Added in version 6.1.0

A deserializer to construct barcode capture from JSON. For most use cases it is enough to use SDCBarcodeCapture.barcodeCaptureFromJSONString: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.

Added in version 6.1.0

Deserializes barcode capture from JSON.

An error is set if the provided JSON does not contain required properties or contains properties of the wrong type.

- updateMode:fromJSONString:error:#
- (nullable SDCBarcodeCapture *)updateMode:(SDCBarcodeCapture *)barcodeCapture
                            fromJSONString:(NSString *)JSONString

Added in version 6.1.0

Takes an existing barcode capture and updates it by deserializing new or changed properties from JSON. See Updating from JSON for details of how updates are being done.

An error is set if the provided JSON does not contain required properties or contains properties of the wrong type.
