Barcode Processor

The barcode processor is a module that will analyze any scanned barcode, parse it and trigger certain actions with regards to the barcode prefix and internal state.

barcodeProcessor.properties

Any entry in barcodeProcessor.properties has the prefix BarcodeProcessorConfig.barcodes. The number that follows groups the properties for a particular processor rule. A rule consists of the following top level properties:

Templates

Properties with the prefix BarcodeProcessorConfig.barcodes.<number>.templates are used to identify the barcode in more detail.

Property	Data Type, Range	Description
BarcodeProcessorConfig.barcodes.<number>.templates.<number>
id	Integer	Unique ID for the template.
name	String	'...name=prefix' identifies the following value as a barcode prefix definition.
value	Integer	Specific barcode prefix to trigger this rule.

POS States

Barcodes might trigger different actions depending on the current app state. Some special barcodes might also not trigger any action at all, if the app is not in the right state. The allowed states are defined by properties with the prefix BarcodeProcessorConfig.barcodes.<number>.posStates

Property	Data Type, Range	Description
BarcodeProcessorConfig.barcodes.<number>.posStates.<number>
id	Integer	Unique ID for the posState entry.
processName	String	Name of the specific process.

Actions

The action to be triggered are defined in BarcodeProcessorConfig.barcodes.<number>.actions.<number>

Property	Data Type, Range	Description
BarcodeProcessorConfig.barcodes.<number>.actions.<number>
id	Integer	Unique ID for the action.
configId	String	A configuration object as defined in the POS config model. Not used in Self Scanning.
BarcodeProcessorConfig.barcodes.<number>.actions.<number>.processReactions.<number>		The reaction/function that should be started.
processName	String	The name of the start process. It must match one of the states defined in BarcodeProcessorConfig.barcodes.<number>.posStates.*
reactionName	String	Name of the function to be started.
BarcodeProcessorConfig.barcodes.<number>.actions.<number>.configParameters.<number>		Function parameters that are extracted from the barcode together with the rules on how to extract them.
configParameters.<number>.name	String	Name of a function parameter that the extracted value should be mapped to.
configParameters.<number>.patternStart	Integer	Defines the start index within the barcode. Note: The first number in the barcode is at position 0.
configParameters.<number>.patternEnd	Integer	Defines the end index within the barcode. Note: The first number in the barcode is at position 0.
configParameters.<number>.trimZeroesLeft	Boolean	Leading zeroes of the extracted values are cut off, if set to true.
configParameters.<number>.trimZeroesRight	Boolean	Trailing zeroes of the extracted values are cut off, if set to true.
configParameters.<number>.decPointPosition	Integer	The extracted value is interpreted as a fixed point number with the defined number of decimal places.
