Finoid Bank Domain Values

Java library for Domain-Driven Design (DDD), providing essential building blocks such as value classes for the bank domain

Modules

• bankdomain-values-core – Core domain value classes for modeling banking identity concepts in a DDD style.
• bankdomain-values-maven-plugin – A Maven plugin that generates the Bank enum from a CSV file published by bankinfrastruktur.se.
• bankdomain-values-wasm – A WebAssembly module that provides a simple validation page for BankID accounts.

What is a domain value class?

A domain value class represents a well-defined concept in the domain model with built-in validation and constraints. Typically immutable, these classes ensure data integrity, enforce domain rules, and increase clarity and maintainability in your codebase.

API

Parse and validate from raw input

BankAccountNumber account = BankAccountNumber.ofString("8351-9, 392 242 224-5");
System.out.println(account.toFormatted(BankAccountFormatter.Format.PRETTY)); // 8351-3922422245

From long or numeric input

BankAccountNumber account = BankAccountNumber.ofNumber(97891111113L);

From clearing and account number

BankAccountNumber account = BankAccountNumber.ofClearingAndAccountNumber(3300, 6205124);

Validation only

boolean isValid = BankAccountNumber.isValid("7000-123456789");
