valuores

Valuores, also known as value objects, are a fundamental concept in object-oriented programming and domain-driven design. They are small, immutable objects that represent a single value or a set of values. Unlike entities, which have a distinct identity and lifecycle, valuores are defined solely by their attributes and are interchangeable if they have the same values.

Valuores are typically used to encapsulate simple data structures, such as money, dates, or ranges. They promote code clarity and maintainability by making the intent of the code explicit. For example, using a Money valuore instead of a simple integer or float makes it clear that the value represents an amount of currency.

The immutability of valuores ensures that once created, their state cannot be changed. This immutability provides several benefits, including thread safety and easier reasoning about the code. When a valuore needs to be modified, a new instance is created with the updated values.

Valuores are often used in conjunction with entities and other valuores to build complex domain models. They help to enforce business rules and invariants by encapsulating the logic related to their values. For instance, a DateRange valuore might enforce that the start date is always before the end date.

In summary, valuores are a powerful tool in software design that promote clarity, immutability, and encapsulation. They are particularly useful in domains where the focus is on the values themselves rather than their identities.
