Delphi: Clean Code: Objects Calisthenics: Rule #4 - First Class Collections

Programming Language: Object Pascal ( Delphi ) "The ThoughtWorks Anthology" - Jeff Bay (2008) Objects Calisthenics: Rule #4: First Class Collections This rule specifies that any class containing a collection should not have any other member variables. It emphasizing that each collection deserves its own dedicated home (class). Such encapsulation turns collections into first-class citizens within the domain, providing a clear home for behaviors related to the collection, such as filtering, aggregation, or applying rules to each element. Wrapping collections thus not only gives them a more defined structural role in the domain, but also elevates domain-specific concepts, making collections integral and well-defined components of your software's architecture. This principle is akin to wrapping primitives, but specifically tailored for collections, ensuring that behaviors have a designated home and that collections are treated with the same care and consideration as other domain-specific elements.
