Class BarcodeDecoder

java.lang.Object
  com.bea.rfid.workflow.util.BarcodeDecoder

public class BarcodeDecoder
extends Object

Converts bar code string or epc to epc id pattern. If the bar code can be converted to a full tag URI, like SSCC, this will return an EPC identity URI string. If the bar code represents only an EPC class, it will be converted to an EPC identity pattern representing the EPC class.

This relies on the company prefix table to get the company prefix out of a bar code like GTIN.

This accepts barcodes in following formats:

String value of barcode with AI fields as String or Barcode tag list (EPC URI in the format urn:connecterra:barcode:[barcodeString]).

This currently supports the following bar code types:

SSCC, GTIN, GLN, GRAI, GIAI are supported. Symbology character decoding is not supported yet. SSCC and SGTIN barcode with AI fields are not supported.

12 digit barcode is processed in following order,

1. Check if it is UCC12(GTIN)

2. Check if it is GIAI

13 digit barcode is processed in following order,

1. Check if it is UCC13(GTIN)

2. Check if it GIAI

14 digit barcode is processed in following order,

1. Check if it is GTIN

2. Check if it is GIAI

18 digit barcode is processed in following order,

1. Check if it is SSCC

2. Check if it is GRAI

3. Check if it is GIAI

GLN is processed in following order

1. Check if is GLN

2. Check if it is GIAI

Note: This class assumes single threaded operation.

Method Detail

decodeFromTagList

public URI decodeFromTagList(List barcodeTagData)
                      throws InvalidBarcodeException,
                             com.connecterra.ale.epc.EPCException

Takes bar code specifed in the given tag list input and decodes the bar code string to an EPC identity URI or EPC identity pattern URI. This is provided as a convenience to use output produced by TagListBuilder. The input list must contain only one entry with the bar code URI. Accepted bar code types and rules used when decoding are specified in the class level documentation.

Parameters:

barcodeTagData - tag list with only one entry, which contains the bar code string.

Returns:

result EPC id URI or EPC id pattern URI

Throws:

InvalidBarcodeException - if the bar code cannot be parsed as any of the supported bar code types

com.connecterra.ale.epc.EPCException - if problem creating EPC from supplied tag data

decode

public URI decode(String barcodeData)
           throws InvalidBarcodeException

Decodes the input bar code string to an EPC identity URI or EPC identity pattern URI. Accepted bar code types and rules used when decoding are specified in the class level documentation.

Parameters:

barcodeData - bar code string

Returns:

result EPC id URI or EPC id pattern URI

Throws:

InvalidBarcodeException - if the bar code cannot be parsed as any of the supported bar code types or problem decoding barcode to a specific encoding
