public class DoLuhnCheckCmdImpl
extends TaskCommandImpl
implements DoLuhnCheckCmd

This DoLuhnCheckCmd Task Command Implementation checks the validity of the credit card number using the LUHN algorithm. If the number is found to be invalid according to the LUHN Algorithm the command throws the ECApplicationException using the Error View Command specified via the setErrorTaskName() method and the errorCode specified in com.ibm.commerce.DoPaymentCmd.ERR_CODE_BAD_CCNUM.

Method Detail

cardNumberCheck

public static boolean cardNumberCheck(java.lang.String astrCCNumber)
Checks the input String of decimal digits according to the LUHN Algorithm. The input string must consist only of decimal digits. Creation date: (03/30/2000 12:47:37 PM)
Parameters:
astrCCNumber - java.lang.String
Returns:
boolean

getCardNumber

protected java.lang.String getCardNumber()
Gets the cardNumber property of the command.

getErrorTaskName

protected java.lang.String getErrorTaskName()
Gets the errorTaskName property of the command.

isReadyToCallExecute

public boolean isReadyToCallExecute()
This method is called by the Command Framework to check if all basic mandatory parameters have been set for this command. This is done before the Framework calls the performExecute method of the command.
Overrides:
isReadyToCallExecute in class AbstractECCommand
Following copied from class: com.ibm.commerce.command.AbstractECCommand
Returns:
boolean - true if we can execute the command false if we canot execute the command

performExecute

public void performExecute()
                    throws ECException
Performs the main business logic of the command.
Specified by:
performExecute in interface ECCommand
Overrides:
performExecute in class AbstractECCommand
Following copied from interface: com.ibm.commerce.command.ECCommand
Throws:
com.ibm.commerce.command.CommandException - The superclass for all ECExceptions.

reset

public void reset()
Resets the instance variables of the command. The reset() method will reset all instance variables. If the command includes any output values that are accessible via getters, then make sure those values are no longer needed before calling this method to reset the instance variables of the command.

This is useful if the command instance is to be called multiple times with different command parameters.

Overrides:
reset in class AbstractECCommand

setCardNumber

public void setCardNumber(java.lang.String astrCardNumber)
Sets the cardNumber property of the command.
Specified by:
setCardNumber in interface DoLuhnCheckCmd
Parameters:
cardNumber - the card number to be used for setting the command property.

setErrorTaskName

public void setErrorTaskName(java.lang.String astrErrorTaskName)
Sets the errorTaskName property of the command.
Specified by:
setErrorTaskName in interface DoLuhnCheckCmd
Parameters:
errorTaskName - the name of the View Command to be used for displaying error information to the Shopper.
