Often a setter is accompanied by a getter, which returns the value of the private member variable. They are also known collectively as accessors . The mutator method is most often used in object-oriented programming , in keeping with the principle of encapsulation .
A JavaBean is a POJO that is serializable, has a no-argument constructor, and allows access to properties using getter and setter methods that follow a simple naming convention. Because of this convention, simple declarative references can be made to the properties of arbitrary JavaBeans.
A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to 'getter' and 'setter' method calls.
The same code as above is auto-generated by Lombok using Java annotations, which is a form of metaprogramming: @AllArgsConstructor @Getter @Setter public class Pet { private String name ; private Person owner ; }
In languages that support access specifiers, the interface of a class is considered to be the set of public members of the class, including both methods and attributes (via implicit getter and setter methods); any private members or internal data structures are not intended to be depended on by external code and thus are not part of the interface.
A property is a subset of a Bean's state. The values assigned to the properties determine the behaviour and appearance of that component. They are set through a setter method and can be obtained by a getter method. Customization A customizer can provide a step-by-step guide that the process must follow to use the component in a specific context ...
In this sense, the idea of encapsulation is more general than how it is applied in object-oriented programming. For example, a relational database is encapsulated in the sense that its only public interface is a query language (such as SQL), which hides all the internal machinery and data structures of the database management system. As such ...
