Barcode Sequence Settings

Defined in framework ScanditBarcodeCapture

BarcodeSequenceSettings
open class BarcodeSequenceSettings : NSObject, NSCopying

Added in version 8.1.0

init
init()

Added in version 8.1.0

Creates a new barcode sequence settings instance. All symbologies are disabled. Make sure to enable the symbologies required by your app before applying the settings to BarcodeSequence with BarcodeSequence.apply().

settings
open func settings(for symbology: Symbology) -> SymbologySettings

Added in version 8.1.0

Gets SymbologySettings specific for the given Symbology.

Note that modifying the returned object doesn’t automatically apply the changes to BarcodeSequence. After you made changes to the symbology settings, call BarcodeSequence.apply() with these BarcodeSequenceSettings to apply them.

EnabledSymbologies
var enabledSymbologies: Set<Symbology> { get }

Added in version 8.1.0

Returns the set of enabled symbologies.

EnableSymbologies
func enableSymbologies(_ symbologies: Set<Symbology>) -> Void

Added in version 8.1.0

This function provides a convenient shortcut to enabling decoding of particular symbologies without having to go through SymbologySettings. By default, all symbologies are turned off and symbologies need to be explicitly enabled.

set
open func set(symbology: Symbology, enabled: Bool) -> Void

Added in version 8.1.0

This function provides a convenient shortcut to enabling/disabling decoding of a particular symbology without having to go through SymbologySettings.

Note

Some 1d barcode symbologies allow you to encode variable-length data. By default, the Scandit Data Capture SDK only scans barcodes in a certain length range.

If your application requires scanning of one of these symbologies, and the length is falling outside the default range, you may need to adjust the active symbol counts for the symbology in addition to enabling it.

set
open func set(value: Any, forProperty property: String) -> Void

Added in version 8.1.0

Sets property to the provided value. Use this method to set properties that are not yet part of a stable API. Properties set through this method may or may not be used or change in a future release.

value
open func value(forProperty property: String) -> Any?

Added in version 8.1.0

Retrieves the value of a previously set property.

filterSettings
open var filterSettings: BarcodeFilterSettings { get, set }

Added in version 8.1.0

Sets and access the barcode filter settings.

idleTimeout
open var idleTimeout: TimeInterval { get, set }

Added in version 8.1.0

The idle timeout, in seconds: the period without any tracked items after which sequencing is automatically paused due to inactivity, turning off the camera.

A value of 0 or less disables the automatic pause, so sequencing keeps running regardless of inactivity.

Defaults to 10 seconds.

initialOrderOnShelf
open var initialOrderOnShelf: Int { get, set }

Added in version 8.5.1

Order on the shelf assigned to the first tracked tray in the next Barcode Sequence session, using the same 0-based numbering as the orderOnShelf reported for tracked trays. Subsequent trays keep incrementing from this value.

Use together with initialOrderOnTray to resume numbering from where a previous session left off, so on-screen row indicators and session data stay aligned with the physical shelf across multiple sessions. See Resuming a Sequence Session.

Values below 0 are clamped to 0. Read when a session starts; a value applied to an already-running session takes effect only on the next session.

Defaults to 0.

initialOrderOnTray
open var initialOrderOnTray: Int { get, set }

Added in version 8.5.1

Order on the tray assigned to the first barcode inside the first tray of the next Barcode Sequence session, using the same 0-based numbering as the orderOnTray reported for tracked barcodes. Later barcodes in that tray increment from this value; new trays in the same session reset their order on the tray to 0, matching the current behavior.

Values below 0 are clamped to 0. Read at session start; changes mid-session do not affect the running session.

Defaults to 0.

Resuming a Sequence Session

MatrixScan Sequence numbers orderOnShelf and orderOnTray from 0 at the start of every session (the on-screen indicators render these as 1-based labels). Applications that scan large surfaces in multiple sessions — for example one shelf row per session — can persist the resume point client-side and pass it to the SDK before the next session begins, so that on-screen indicators and session data continue matching the physical layout.

Set BarcodeSequenceSettings.initialOrderOnShelf and BarcodeSequenceSettings.initialOrderOnTray before applying settings, then start or reset the mode. The seeded order on the shelf applies to every tray in that session (the first tray reports the seeded value as its orderOnShelf, subsequent trays continue counting up); the seeded order on the tray applies only to the first barcode of the first tray (later barcodes in that tray increment from it; new trays in the same session reset to 0).
