Barcode Count Session
Defined in library scandit_datacapture_barcode_count
- BarcodeCountSession
class BarcodeCountSessionAdded in version 6.17.0
The count session contains all the currently tracked barcodes and changes that were made specifically in the last processed frame.
Important
The count session should only be accessed from within didScan() to which it is provided as an argument. It is not safe to be accessed from anywhere else since it may be concurrently modified.
Specifically no reference to recognizedBarcodes should be kept and traversed outside of didScan(). Instead a copy of the lists should be made to avoid concurrent modification. The individual tracked barcodes can be referenced without copying as they are not further modified.
- recognizedBarcodes
Map<int, TrackedBarcode> get recognizedBarcodes
Added in version 6.17.0

- frameSequenceId
int get frameSequenceId
Added in version 6.17.0

Important
As long as there is no interruptions of frames coming from the camera, the frameSequenceId will stay the same.
