Field Detail

address

private volatile UserAddress address

buyerCompany

private volatile String buyerCompany

buyerFamilyName

private volatile String buyerFamilyName

buyerGivenName

private volatile String buyerGivenName

cardCode

private volatile BigDecimal cardCode

The CCV, Card Code.

cardCodeString

@Deprecated
private volatile String cardCodeString

Deprecated.

The CCV, Card Code, stored as a string. This is an historical hack due to issues with properly formatting CCVs for Authorize.Net and should be phased out as soon as those bugs have been fixed.

cardNumber

private volatile BigDecimal cardNumber

The credit-card number

credentialType

private CredentialType credentialType

The type of credentials presented. See CredentialType for all valid values. Note that at present we only actually support credit cards and gift cards.

private Date expiry

The expiry date of a credit card (used for validation)

Constructor Detail

PaymentCredential

public PaymentCredential()

Method Detail

doesNumberMatchLuhnChecksum

private static boolean doesNumberMatchLuhnChecksum(BigDecimal number)

Perform Luhn algorithm validation upon the credit-card number supplied.

Parameters:

number - An arbitrary-length credit-card number

Returns:

True, if the number given is potentially valid as a credit-card number

getFriendlyName

public static String getFriendlyName(CredentialType type)

Parameters:

type - a type of credentials

Returns:

a "friendly" (but possibly verbose) description of the type of transaction credentials, suitable for displaying to the end-user. This is used by, e.g. UnsupportedCredentialException to display "pretty" error messages.

verifyIBC

public static int verifyIBC(String ibcCode)
                     throws NotImplementedException,
                            AlreadyUsedException,
                            NotFoundException

Parameters:

ibcCode - WRITEME

Returns:

WRITEME

Throws:

NotImplementedException - WRITEME

AlreadyUsedException - WRITEME

NotFoundException - WRITEME

applyTo

public void applyTo(AimTransaction xact)
             throws UnsupportedCredentialException

Apply a (credit-card only) set of payment credentials to an Authorize.Net one-time-purchase (AIM, Advanced Integration Method) object.

At present, this (or applyTo(ARBPayment)) are the only supported way to extract the card information once it's entered into this object; however, the last 4 digits of the card number are visible via #toString()

Parameters:

xact - An Authorize.Net transaction in the form of AimTransaction

Throws:

UnsupportedCredentialException - if attempting to apply a credential type other than MasterCard or VISA

applyTo

public void applyTo(ARBNameAndAddress billTo)

WRITEME: document this method (brpocock@star-hope.org, Sep 11, 2009)

Parameters:

billTo - WRITEME

applyTo

public void applyTo(ARBPayment payment)
             throws UnsupportedCredentialException

Apply the credit-card information to the Authorize.net ARBPayment object.

At present, this (or applyTo(AimTransaction)) are the only supported way to extract the card information once it's entered into this object; however, the last 4 digits of the card number are visible via #toString()

Parameters:

payment - The ARB Payment object to which we want to append the card information.

Throws:

UnsupportedCredentialException - if this is not a credit-card credentials bundle

getAddress

public UserAddress getAddress()

Returns:

UserAddress address

getBuyerCompany

public String getBuyerCompany()

Returns:

the buyerCompany

getBuyerFamilyName

public String getBuyerFamilyName()

Returns:

String buyerFamilyName

getBuyerGivenName

public String getBuyerGivenName()

Returns:

String buyerGivenName

getCredentialType

public CredentialType getCredentialType()

Returns:

the credentialType

getExpiryMonth

public int getExpiryMonth()

WRITEME: document this method (brpocock@star-hope.org, Sep 11, 2009)

Returns:

WRITEME

getExpiryYear

public int getExpiryYear()

WRITEME: document this method (brpocock@star-hope.org, Sep 11, 2009)

Returns:

WRITEME

getLastFour

private String getLastFour()

Returns:

The last four digits of a credit-card number. Used by toString() and only accessible thereby.

setBuyerCompany

public void setBuyerCompany(String company)

WRITEME: document this method (brpocock@star-hope.org, Sep 11, 2009)

Parameters:

company - WRITEME

setBuyerInfo

public void setBuyerInfo(String buyerGivenName1,
                         String buyerFamilyName1,
                         UserAddress address1)

WRITEME: document this method (brpocock@star-hope.org, Sep 23, 2009)

Parameters:

buyerGivenName1 - WRITEME

buyerFamilyName1 - WRITEME

address1 - WRITEME

setCardCode

public void setCardCode(BigDecimal num)

Parameters:

num - The CCV, Card Code Verification, number (3 or 4 digits)

setCardCode

public void setCardCode(String num)

Parameters:

num - The CCV, Card Code Verification, number (3 or 4 digits)

setCardCodeAsString

@Deprecated
public void setCardCodeAsString(String code)

Deprecated. use setCardCode(BigDecimal)

This is an historical hack from a problem with properly formatting card codes beginning with zeroes.

Parameters:

code - The CCV, Card Code Verification, number (3 or 4 digits)

setCardNumber

public void setCardNumber(BigDecimal num)
                   throws NumberFormatException

Parameters:

num - The credit-card number (usually 16 digits)

Throws:

NumberFormatException - if the card number does not match checksum

setCardNumber

public void setCardNumber(String num)
                   throws NumberFormatException

Set a card number from a user-supplied string. This method removes non-digit contents before attempting to store the value as a BigDecimal, so it should be used for user-supplied inputs that might contain spaces or dashes, or other random line noise.

Parameters:

num - The presumed credit-card number, possibly containing spaces or dashes.

Throws:

NumberFormatException - if the card number has an invalid length, non-digit contents, or does not match a correct checksumming for the type of card provided

setCredentialType

public void setCredentialType(CredentialType credentialType1)

Parameters:

credentialType1 - the credentialType to set

setExpiry

public void setExpiry(Date d)

public void setIBCCard(String ibcCode)
                throws NotImplementedException

Parameters:

ibcCode - WRITEME

Throws:

NotImplementedException - WRITEME

shred

public void shred()

Discard all credential information

toString

public String toString()

This is an overriding method.

Overrides:

toString in class Object

See Also:

Object.toString()

verifyCredentials

public void verifyCredentials()
                       throws DataException

Perform basic validation upon the credentials.

For credit-cards, verify that the credentials appear to have a valid credit-card number.

For electronic payments of other kinds, perform basic validation of credential values to ensure that they appear to be basically plausible.

XXX right now, this only actually checks the first digit against VISA/MasterCard selection. This should do proper checksum checks against the full number...

Throws:

DataException - if the card number is invalid (impossible), or the type of credentials for payment presented are not set to a valid/supported type (currently VISA or MasterCard)
