Enum TransactionResult

java.lang.Object

java.lang.Enum<TransactionResult>

com.yello.api.payment.emv.TransactionResult

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TransactionResult>

public enum TransactionResult
extends java.lang.Enum<TransactionResult>

List of EMV transaction results

List of results that can be returned as part of the TransactionStatus class, representing the outcome of an EMV transaction. The TransactionStatus is returned following a call to the method Transaction.startTransaction(com.yello.api.payment.emv.TransactionType, java.math.BigDecimal, java.math.BigDecimal) or the method Transaction.startTransaction(com.yello.api.payment.emv.TransactionConfiguration, com.yello.api.payment.emv.TransactionType, java.math.BigDecimal, java.math.BigDecimal) of the Transaction singleton class.

For more information about starting an EMV transaction see the Transaction singleton class.

Enum Constant Detail

APPROVED

public static final TransactionResult APPROVED

The EMV transaction has been approved.

DECLINED

public static final TransactionResult DECLINED

The EMV transaction has been declined.

COMM_TIMEOUT

public static final TransactionResult COMM_TIMEOUT

Communication timeout while waiting for the EMV transaction to complete.

IO_ERROR

public static final TransactionResult IO_ERROR

An IO error has occurred while performing the EMV transaction.

PROCESSING_ERROR

public static final TransactionResult PROCESSING_ERROR

EMV processing error (see below for more information).

A processing error is generated:

• either if the user cancels the EMV transaction before card insertion or card presentation (for EMV contactless);
• or if the card is not presented or inserted within a given EMV transaction time frame;
• or if any internal errors are encountered by the EMV kernel during transaction processing.

UNKNOWN

public static final TransactionResult UNKNOWN

Unknown error

Method Detail

values

public static TransactionResult[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TransactionResult c : TransactionResult.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TransactionResult valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getByte

public byte getByte()

Gets the byte value of the Transaction result

Returns:

byte value

toString

public static java.lang.String toString(TransactionResult result)

fromByte

public static TransactionResult fromByte(byte value)

Get a TransactionResult from a byte value

Parameters:

value - byte value of the TransactionResult

Returns:

TransactionResult if byte value is valid otherwise return null
