Basic Concepts of Processed Transaction Resource

Overview​

The Processed Transaction Resource is a class that provides methods to handle processed transactions. It is annotated with the path /processedTransaction and produces JSON responses. The class includes methods to retrieve and manipulate processed transaction data, such as getting processed transactions, debiting or crediting accounts, transferring funds, and creating or deleting customers and accounts.

Methods in Processed Transaction Resource​

The class includes several methods to handle different types of transactions. These methods are designed to retrieve, process, and manipulate transaction data, and they produce JSON responses containing the transaction details.

getProcessedTransactionExternal​

The getProcessedTransactionExternal method retrieves processed transactions based on a limit and offset. It calls the getProcessedTransactionInternal method to perform the actual data retrieval.

The getProcessedTransactionExternal method is defined here. It retrieves processed transactions based on a limit and offset, and calls the getProcessedTransactionInternal method to perform the actual data retrieval.

	@GET
	@Produces(MediaType.APPLICATION_JSON)
	public Response getProcessedTransactionExternal(
			@QueryParam(LIMIT) Integer limit,
			@QueryParam(OFFSET) Integer offset)
	{
		Response myResponse = getProcessedTransactionInternal(limit, offset);
		HBankDataAccess myHBankDataAccess = new HBankDataAccess();
		myHBankDataAccess.terminate();
		return myResponse;
	}

getProcessedTransactionInternal​

The getProcessedTransactionInternal method fetches processed transactions from the database, processes each transaction, and constructs a JSON response containing the transaction details.

The getProcessedTransactionInternal method is defined here. It fetches processed transactions from the database, processes each transaction, and constructs a JSON response containing the transaction details.

	public Response getProcessedTransactionInternal(
			@QueryParam(LIMIT) Integer limit,
			@QueryParam(OFFSET) Integer offset)
	{

		if (offset == null)
		{
			offset = 0;
		}
		if (limit == null)
		{
			limit = 250000;
		}
		JSONObject response = new JSONObject();
		JSONArray processedTransactionsJSON = null;
		int numberOfProcessedTransactions = 0;
		Integer sortCode = this.getSortCode();

		com.ibm.cics.cip.bankliberty.web.db2.ProcessedTransaction myProcessedTransaction = new com.ibm.cics.cip.bankliberty.web.db2.ProcessedTransaction();
		com.ibm.cics.cip.bankliberty.web.db2.ProcessedTransaction[] processedTransactions = null;

processTransfer​

The processTransfer method processes bank-to-bank transfer records and adds relevant details to the JSON response.

The processTransfer method is defined here. It processes bank-to-bank transfer records and adds relevant details to the JSON response.

	private JSONObject processTransfer(JSONObject proctran,
			ProcessedTransaction processedTransaction)
	{
		// Process bank to bank transfer records
		if (processedTransaction.getType()
				.compareTo(PROCTRAN.PROC_TY_TRANSFER) == 0)
		{
			proctran.put(JSON_TARGET_ACCOUNT,
					processedTransaction.getTargetAccountNumber());
			proctran.put(JSON_TARGET_SORT_CODE,
					processedTransaction.getTargetSortcode());
		}
		return proctran;
	}

processDeleteCreateCustomer​

The processDeleteCreateCustomer method deals with creating and deleting customer records and adds relevant details to the JSON response.

The processDeleteCreateCustomer method is defined here. It deals with creating and deleting customer records and adds relevant details to the JSON response.

	private JSONObject processDeleteCreateCustomer(JSONObject proctran,
			ProcessedTransaction processedTransaction, DateFormat myDateFormat)
	{
		// Deal with create account and delete customer
		if (processedTransaction.getType()
				.compareTo(PROCTRAN.PROC_TY_BRANCH_DELETE_CUSTOMER) == 0
				|| processedTransaction.getType()
						.compareTo(PROCTRAN.PROC_TY_WEB_DELETE_CUSTOMER) == 0
				|| (processedTransaction.getType()
						.compareTo(PROCTRAN.PROC_TY_BRANCH_CREATE_CUSTOMER) == 0
						|| processedTransaction.getType().compareTo(
								PROCTRAN.PROC_TY_WEB_CREATE_CUSTOMER) == 0))
		{
			proctran.put(JSON_DATE_OF_BIRTH,
					myDateFormat.format(processedTransaction.getDateOfBirth()));
			proctran.put(JSON_CUSTOMER_NAME,
					processedTransaction.getCustomerName());
			proctran.put(JSON_CUSTOMER, processedTransaction.getCustomer());
		}
		return proctran;
	}

processDeleteCreateAccount​

The processDeleteCreateAccount method deals with creating and deleting account records and adds relevant details to the JSON response.

The processDeleteCreateAccount method is defined here. It deals with creating and deleting account records and adds relevant details to the JSON response.

	private JSONObject processDeleteCreateAccount(JSONObject proctran,
			ProcessedTransaction processedTransaction, DateFormat myDateFormat)
	{
		// Deal with create account and delete account
		if (processedTransaction.getType()
				.compareTo(PROCTRAN.PROC_TY_BRANCH_DELETE_ACCOUNT) == 0
				|| processedTransaction.getType()
						.compareTo(PROCTRAN.PROC_TY_WEB_DELETE_ACCOUNT) == 0
				|| processedTransaction.getType()
						.compareTo(PROCTRAN.PROC_TY_BRANCH_CREATE_ACCOUNT) == 0
				|| processedTransaction.getType()
						.compareTo(PROCTRAN.PROC_TY_WEB_CREATE_ACCOUNT) == 0)
		{
			proctran.put(JSON_ACCOUNT_TYPE,
					processedTransaction.getAccountType());
			proctran.put(JSON_LAST_STATEMENT, myDateFormat
					.format(processedTransaction.getLastStatement()));
			proctran.put(JSON_NEXT_STATEMENT, myDateFormat
					.format(processedTransaction.getNextStatement()));
			proctran.put(JSON_CUSTOMER, processedTransaction.getCustomer());
		}
