Id<T> class abstract

Represents a generic identifier for entities within the domain model.

This abstract class extends SingleTypeValueObject to encapsulate an identifier value of a specific type T. It provides a standard way to handle entity identifiers across the domain, ensuring they are treated as value objects with value-based equality.

The class overrides the equality and hash code methods to compare identifier instances based on their encapsulated value, and provides a toString method for convenient string representation of the identifier.

Usage:

class UserId extends Id<String> {
  UserId(String value) : super(value);
}
