Field Details

ScanDataDef

public byte[] ScanDataDef

Default value of ScanData property. Default: Zero-length byte array. Can be overwritten by objects derived from JposDevice within the changeDefaults method.

DecodeData

public boolean DecodeData

UPOS property DecodeData.

ScanData

public byte[] ScanData

UPOS property ScanData.

ScanDataLabel

public byte[] ScanDataLabel

UPOS property ScanDataLabel.

ScanDataType

public int ScanDataType

UPOS property ScanDataType.

Constructor Details

ScannerProperties

public ScannerProperties(int dev)

Constructor. Sets ExclusiveUse to ExclusiveYes to match the ScannerInterface device model.

Parameters:

dev - Device index

Method Details

initOnOpen

public void initOnOpen()

Description copied from class: JposCommonProperties

Initialization of properties that must be initialized during open.

Overrides:

initOnOpen in class JposCommonProperties

clearDataProperties

public void clearDataProperties()

Description copied from class: JposCommonProperties

Clear data properties. Performed during ClearInput and ClearInputProperties.

Overrides:

clearDataProperties in class JposCommonProperties

decodeData

public void decodeData(boolean flag)
                throws jpos.JposException

Description copied from interface: ScannerInterface

Final part of setting DecodeData. Can be overwritten within derived classes, if necessary. This method will be called only if the following plausibility checks lead to a positive result:

• Device has not been closed,
• internal property AllowAlwaysSetProperties is true or flag equals the previous value of DecodeData.

Specified by:

decodeData in interface ScannerInterface

Parameters:

flag - New DecodeData value

Throws:

jpos.JposException - If an error occurs
