Quotes About Encapsulation

confidence. He contained worlds.

My favorite language for maintainability is Python. It has simple, clean syntax, object encapsulation, good library support, and optional named parameters.

The problem with traditional approaches to abstraction and encapsulation is that they aim at complete information hiding. This characteristic anticipates being able to eliminate programming from parts of the software development process, those parts contained within module boundaries. As we've seen, though, the need to program is never eliminated because customization, modification, and maintenance are always required-that is, piecemeal growth.

When experiences or emotions become too overwhlming, the mind clevely encapsulates the material and stores it for safe-keeping. Many people respond this way in the face of trauma, but the additional step that occurs in this process, in the case of DID, is the formation of distinct ego states that carry the experience.

A class, in Java, is where we teach objects how to behave.

We do not want to expose the details of our data. Rather we want to express our data in abstract terms. This is not merely accomplished by using interfaces and/or getters and setters. Serious thought needs to be put into the best way to represent the data that an object contains. The worst option is to blithely add getters and setters.

This means that the UI and the database can be plugins to the business rules. It means that the source code of the business rules never mentions the UI or the database.

If your function must change the state of something, have it change the state of its owning object.

Encapsulation is broken because all functions in the path of a throw must know about details of that low-level exception. Given that the purpose of exceptions is to allow you to handle errors at a distance, it is a shame that checked exceptions break encapsulation in this way.

Os padrôes facilitam a reutilização de ideias e compomentes, recrutam pessoas com experiência considerável, encapsulam boas ideis e conectam os compomentes. Entretanto, o processo de criação de padôes pode, ás vezes, ser muito longo para que o mercado fique á espera deles, e alguns padrôes acabam se desviando das necessidades reais das pessoas a quem eles pretendem servir.

The source code of higher-level services must not contain any specific physical knowledge (e.g., a URI) of any lower-level service.

But then closely related concepts should not be separated into different files unless you have a very good reason. Indeed, this is one of the reasons that protected variables should be avoided.

More precisely, the Law of Demeter says that a method f of a class C should only call the methods of these: • C • An object created by f • An object passed as an argument to f • An object held in an instance variable of C

ENTITIES Entities encapsulate enterprise-wide Critical Business Rules. An entity can be an object with methods, or it can be a set of data structures and functions. It doesn't matter so long as the entities can be used by many different applications in the enterprise.

We repress our bodies to purchase a soul that time cannot destroy; we sacrifice pleasure to buy immortality; we encapsulate ourselves to avoid death. And life escapes us while we huddle within the defended fortress of character.

I think human beings have evolved to appreciate narrative, in the same way that we have evolved to learn language. What is narrative, after all, but a kind of super-language, where stories, like words, are ways of encapsulating information?

We contain the other, hopelessly and forever.

My DVD cellophane was put on by a psychiatrist. It was shrink-wrapped.

Take what varies and "encapsulate" it so it won't affect the rest of your code.

methods in objects are properties too. They just happen to have a function assigned to them.

Using a method to change a property is another example of encapsulation whereby we can often improve the maintainability and extensibility of code by letting an object worry about how it gets things done. It's

Provide an interface for creating families of related or dependent objects without specifying their concrete classes.

Keep Your Design Modular Modularity's goal is to make each routine or class like a black box: You know what goes in, and you know what comes out, but you don't know what happens inside.

The concept of modularity is related to information hiding, encapsulation, and other design heuristics. But sometimes thinking about how to assemble a system from a set of black boxes provides insights that information hiding and encapsulation don't, so the concept is worth having in your back pocket.
