Constructor Detail

DecreaseCmdBuild

public DecreaseCmdBuild(PoClass poClass,
                        byte sfi,
                        int counterNumber,
                        int decValue)

Instantiates a new decrease cmd build from command parameters.

Parameters:

poClass - indicates which CLA byte should be used for the Apdu

sfi - SFI of the file to select or 00h for current EF

counterNumber - >= 01h: Counters file, number of the counter. 00h: Simulated Counter file.

decValue - Value to subtract to the counter (defined as a positive int <= 16777215 [FFFFFFh])

Throws:

java.lang.IllegalArgumentException - - if the decrement value is out of range

java.lang.IllegalArgumentException - - if the command is inconsistent

public DecreaseRespPars createResponseParser(org.eclipse.keyple.core.card.message.ApduResponse apduResponse)

Create the response parser matching the builder

Specified by:

createResponseParser in class AbstractPoCommandBuilder<DecreaseRespPars>

Parameters:

apduResponse - the response data from the the card

public int getCounterNumber()

Returns:

the counter number

Since:

0.9

getDecValue

public int getDecValue()

Returns:

the decrement value
