| enum GrabbaBarcodeSymbology : NSInteger |
Enumeration of supported barcode symbologies.
This is typically used in conjunction with the GrabbaBarcodeData class, where it provides identification of barcode symbologies for scanned barcodes.
The GrabbaSymbologyUnknown value is a sentinel which signifies that the barcode symbology could not be detected (e.g. if it does not match any of the supported types); the other values all represent legitimate symbologies.
| enum GrabbaBER_ID_Class : NSInteger |
Set of supported ID class field values for BER Type structures (part of BER-TLV)
| enum GrabbaButtonBehaviour : NSInteger |
Enumeration of supported button behaviours.
This enumeration describes the set of button behaviours directly supported by the driver. It applies to the left and right buttons of a connected Grabba device; they may be configured to behave identically or independently.
| Enumerator | |
|---|---|
| GrabbaButtonCallbackOnly | Button events only trigger callbacks (default behaviour) Pressing or releasing the buttons on the Grabba device has no effect within the driver beyond triggering callbacks to any active GrabbaButtonListener objects (including subclasses). Application code may use these events to trigger desired processing, but there is no requirement to do so. |
| GrabbaButtonBarcodePressToScan | Button events control barcode scans in addition to triggering callbacks. Pressing the button will trigger a barcode scan if one is not already active. This scan will continue until any of the following conditions are met:
This behaviour is the equivalent of invoking startScan when buttons are pressed and stopScan when buttons are released. |
| GrabbaButtonProxcardPressToScan | Button events control proxcard/RFID scans in addition to triggering callbacks. Pressing the button will trigger a proxcard/RFID scan if one is not already active. This scan will continue until any of the following conditions are met:
This behaviour is the equivalent of invoking startScan when buttons are pressed and stopScan when buttons are released. |
| enum GrabbaErrorCodeValue : NSInteger |
Set of supported error code values for the GrabbaErrorCode class.
| enum GrabbaFingerprintImageTypeID : NSInteger |
Fingerprint image types for capture and enrolment functions.
| enum GrabbaFingerprintTemplateTypeID : NSInteger |
Fingerprint template types for capture and enrolment functions.
| enum GrabbaFingerprintUserMessageTypeID : NSInteger |
Enumeration of user messages which may be generated during fingerprint reader operations.
| enum GrabbaMRZ_Format : NSInteger |
Enumeration of MRZ formats as defined by ICAO 9303, plus a sentinel value for unknown/invalid text.
Five sizes of MRZ are specified in ICAO 9303 - TD1, TD2, TD3, MRV-A and MRV-B. Passports use the TD3 format, official travel documents use the TD1 or TD2 formats, and visas use the MRV-A or MRV-B formats.
The specifications may be found in:
| enum GrabbaProxcardTypeID : NSInteger |
RFID and proximity card type identifiers which are supported by the driver.
This is typically used in conjunction with the GrabbaProxcardData class, where it provides identification of card/tag types upon successful scans.
The GrabbaProxcardTypeUnknown value is a sentinel which signifies that the card/tag could not be detected (e.g. if it does not match any of the supported types); the other values all represent legitimate types.
| enum GrabbaSmartcardBaud : NSInteger |
Set of driver-supported baud parameter values, with representations matching those in ISO/IEC 7816-3.
This enumeration lists the valid values for parameter Di, which is the indicated value of the baud rate adjustment integer.
The representation used here matches that of the lower (less significant) nibble of bytes TA1 (ATR) and PPS1 (PPS) in ISO/IEC 7816-3.
The default value is GrabbaSmartcardBaud1 (Di = 1).
| enum GrabbaSmartcardClock : NSInteger |
Set of driver-supported clock values, with representations matching those in ISO/IEC 7816-3.
This enumeration covers the valid combinations of a pair of parameters:
The representation used here matches that of the upper (more significant) nibble of bytes TA1 (ATR) and PPS1 (PPS) in ISO/IEC 7816-3.
The default value is GrabbaSmartcardClock372_5M, with Fi = 372 and f_max = 5MHz.
| enum GrabbaSmartcardInterfaceID : NSInteger |
Enumeration of contact smart card interfaces.
For Grabba devices containing more than one contact smart card interface, this enumeration allows selection of which interface (and, if present, card) is to be accessed for each command (e.g. APDU exchange).
Contact smart card interfaces provided by Grabba devices fall into one of two categories:
Grabba devices with contact smart card support will contain either a slot interface, a SAM interface, or both. Devices with more than one slot interface and/or more than one SAM interface may be added in future, but are not supported by the current version of the driver.
| Enumerator | |
|---|---|
| GrabbaSmartcardPrimarySlot | First slot interface (if present) |
| GrabbaSmartcardPrimarySAM | First SAM interface (if present) |
| enum GrabbaSmartcardProtocolID : NSInteger |
Set of driver-supported protocol (T) values, with representations matching those in ISO/IEC 7816-3.
The default value is GrabbaSmartcardProtocolHalfDuplexChar (T0).
