java - What is Law of Demeter? - Stack Overflo

  1. What the Law is quite clearing saying is that you shouldn’t access the Street in this structure. As in, you shouldn’t even know it’s there. Don’t trick the definition by introducing wrapper methods! There is a deeper design issue here that needs to be addressed (no pun intended)!
  2. Some, including the Wikipedia Article on the Law of Demeter, argue that the Law implies the usage of “Wrapper” methods to get around calling methods on foreign objects, like this:
  3. Law of Demeter (LoD). Variants and Alternative Names. High Cohesion (HC): Adhering to the Law of Demeter often results in additional methods that mirror methods of aggregated objects
  4. The law of Demeter is sometimes a pain to work with but it makes your codebases easier to refactor and test when there's no calls to foo.bar.qux.makeWidget() inside a WidgetFactory class

In pure OOP, the Law of Demeter is not a suggestion, it is the law of the land. This dive into the law covers common uses as well as flaws in interpretation.

While there are many good qualities about the Law of Demeter, there are consequences to following this “law” as well:Note that coupling may be defined as the degree of interdependence that exists between software modules and how closely such modules are connected to each other. The more the coupling between the components in an application, the harder it becomes to modify and maintain it over time. It's always a good practice to design systems that are easier to test and maintain by ensuring that the components in an application are loosely coupled. You can learn more on cohesion and coupling from my article here.

The Law of Demeter is a very well-defined set of rules for Object-Oriented development. Following these rules in letter and spirit takes little effort if one is applying good Object-Oriented Design principles anyway. The Law of Demeter for functions [LH89] attempts to minimize coupling between modules in any given program. It tries to prevent you from reaching into an object to gain access to a third object's methods

Some explanations of the Law concentrate on so-called “chain calls”, that is, expressions which contain multiple dereferencings. Or stated plainly, multiple “dots”, like this: Fluent or Law of Demeter? Serban Gavrus. Abstract The Law of Demeter is one of the most widely known programming principle, it‟s easy to respect and it assures some important code quality aspect We were just talking about this at work, whether or not it was possible to implement the Law of Demeter in PMD. There's a guideline to prevent this called the Law of Demeter Just as it’s helpful to see good examples of what you should do, it can also be helpful to see examples of what you shouldn’t do in your code. Let’s take a look at some “bad examples” of the Law of Demeter in Java.

Law of Demeter also known as the principle of least knowledge is a coding principle, which says that a module should not know about the inner details of the objects it manipulates In summary, all of the rules above can be summarized by saying you should avoid invoking methods of a member object returned by another method. In modern object-oriented languages the identifier used is dot or ->. Therefore Demeter's law is violated when the code has more than one step between classes. For example, the following code shows an example in which Demeter's law is violated: Short introduction into Law of Demeter with examples of satisfaction and violation that demonstrates benefits of following the style as well as potential comp

While developing software I often see Law of Demeter violations. These days I seem to see more of this, probably because Ruby on Rails allows you to easily navigate between objects based on table.. By Joydip Kanjilal, Columnist, InfoWorld | There are two arguments against this line of reasoning. One is that it still just tries to work around the Law instead of heeding its advice. And the second is that direct access to fields arguably still qualifies as “sending a message,” since it is still just communication between two objects.The Law of Demeter for functions requires that a method M of an object O may only invoke the methods of the following kinds of objects:

Fragrance Families. Blending Basics. About Demeter public final class Car { private final Owner owner; public Street getOwnerAddressStreet() { return owner.getAddressStreet(); } ... } This is almost certainly a violation of the Law, since all those objects (owner, address) are presumably already-existing instance variable values, to which the Law prohibits access.

And doesn't Law of Demeter imply that chaining is bad? In this case (assuming the design pattern was acceptable in all other ways), the Law of Demeter would allow this, since it is globally accessible.. Some interpretations of the Law argue that since chain-calls are not allowed, fluent APIs are also forbidden. Fluent APIs are created to allow syntactically easy usage of a library or set of classes. They look like this:

Now, refer to the LawOfDemeterExample class shown above. The code is self-explanatory. You might now wonder if the Law of Demeter applies only to methods. The answer is "No". The Law of Demeter principle applies to properties as well. The Law of Demeter (English: Law of Demeter, in short: LoD ) is a draft directive in object-oriented software development. It essentially says that objects should only communicate with objects in their.. objectA.getObjectB().getObjectC().doSomething(); When you write code like this, not only are you exposing yourself to changes in the ObjectA class, you’re also exposing yourself to changes that may occur in ObjectB and ObjectC as well. Here are just a few ways these calls make your class more fragile: Faraday's law of electromagnetic induction (referred to as Faraday's law) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an..

The following steps show you must implement the code to respect Demeter’s Law and obtain a less coupled code. So, the first step is to create the interface which will be implemented in our concrete classes: The thing is that the Law of Demeter is not about the number of dots. This law is about reducing the coupling and improving the encapsulation. When we are talking about data structures like data..

You should not expect Class1 to call a method from Class3. Class1 should not have the knowledge about Class3 methods because its not passed directly as a parameter, is not a direct dependency or is instantiated by Class1. Instead you should handle any logic for Class3 in Class2 itself. Demeter definition: 1. in Greek mythology (= ancient stories), the goddess (= female god) of grain and the harvest.

These already existing objects must have a reference to them, otherwise, nobody would be able to access them. Therefore these objects must be referenced from fields (variables) of other objects. Rule #5 allows global objects, so that leaves us with objects in instance variables. The Law of Demeter or principle of least knowledge is a design guideline for developing software, particularly object-oriented programs.

public final class Garage { public void isAllowed(Car car) { Owner owner = car.getOwner(); // Allowed? ... } } This was a quick overview of the Law of Demeter. This is one of the laws you should follow and understand for creating decoupled code. The advantage here is that by following this law your code becomes more maintainable and adaptable which is important when creating object oriented code. Every class should be able to work on its own and should not know about the details that it should not know. You can only go one level deep. So always think before coding!This might be considered unexpected. So that means while calling the getter itself might be technically legal, we can’t actually use the result. It seems getter methods violate the Law of Demeter almost by design.

Introducing Demeter and its Laws

An Object-Oriented developer should be aware that more often than not, these opinions come from a background of different programming paradigms, in which the Law of Demeter might very well have a different weight or even interpretation than in Object-Orientation.That means that the Law prohibits “sending a message” to any already existing object that is held in instance variables of other classes, unless it is also held by our class or passed to us as method parameters.

The following “refactored” code still violates the Law:In the early days of Object-Orientation, objects were supposed to “send messages” to each other. That is how they communicated. So the term “objects to which M sends a message” roughly translates to “objects used by M,” or in a more practical definition “objects on which M calls a method on.”Published at DZone with permission of Robert Brautigam .

There are well-known abstract concepts in Object-Oriented programming, like encapsulation, cohesion, and coupling, that could be theoretically used to generate clear designs and good code. While these are all very important concepts, they are just not pragmatic enough to be directly useful for development. One has to interpret these concepts, and with that, they become somewhat subjective and start to depend on people’s experience and knowledge. Law of Demeter — The Law of Demeter (LoD) or Principle of Least Knowledge is a design guideline for developing software, particularly object-oriented programs. In its general form, the LoD is a specific case of loose coupling The Law of Demeter principle takes advantage of encapsulation to achieve this isolation and reduce coupling amongst the components of your application. This helps in improving the code quality and promotes flexibility and easier code maintenance. The benefit of adhering to the Law of Demeter is that you can build software that is easily maintainable and adaptable to future changes.

The Law of Demeter is a design guideline with as goal to create loose coupling between objects.  It is also know as the principle of least knowledge. This is the law for methods. The less a method knows about other objects methods, the less coupling you have.Whenever you talk to a good, experienced programmer, they will tell you that “loosely coupled” classes are important to good software design. The Law of Demeter for functions (or methods, in Java) attempts to minimize coupling between classes in any program. In short, the intent of this “law” is to prevent you from reaching into an object to gain access to a third object’s methods.

Law of Demeter is more of a guideline than a principle to help reduce coupling between components. There are below general outcome of the code when we avoid this law According to Law of Demeter, a class should only interact with those that are considered its immediate friends This is a violation of the Law of Demeter. The method received the parameter person, so all method calls on this object are allowed. However, calling any methods (in this case getBytes()) on the object returned by either getName() or getPhoto() is not allowed. Assuming standard getters, these objects are already existing objects in other objects’ instance variables, therefore they are exactly the kind of objects this method should not have access to.The same can be said for other concepts like the Single Responsibility Principle, or the Open/Closed Principle, etc. These allow a very wide margin for interpretation, so the practicality, the direct usefulness, is therefore diminished.
