C# have records which provide immutability and equality testing. [1] The record is sealed to prevent inheritance. [2] It overrides the built-in ToString() method. [3]This example implementation includes a static method which can be used to initialize a new instance with a randomly generated globally unique identifier (GUID).
Go type embedding avoids the need for forwarding methods. [12] Java provides default interface methods since version 8. [4]: 104 Project Lombok [13] supports delegation using the @Delegate annotation on the field, instead of copying and maintaining the names and types of all the methods from the delegated field. [14]
JSDoc differs from Javadoc, in that it is specialized to handle JavaScript's dynamic behaviour. [2] An early example using a Javadoc-like syntax to document JavaScript was released in 1999 with the Netscape/Mozilla project Rhino, a JavaScript run-time system written in Java. It included a toy "JSDoc" HTML generator, versioned up to 1.3, as an ...
There are methods that a subclass cannot override. For example, in Java, a method that is declared final in the super class cannot be overridden. Methods that are declared private or static cannot be overridden either because they are implicitly final. It is also impossible for a class that is declared final to become a super class. [9]
Extension methods might 'clutter' the automatic completion features of code editors, such as Visual Studio's IntelliSense, hence they should either be in their own namespace to allow the developer to selectively import them or they should be defined on a type that is specific enough for the method to appear in IntelliSense only when really ...
override (or asymmetric sum): an operation that forms a new trait by adding methods to an existing trait, possibly overriding some of its methods; alias: an operation that creates a new trait by adding a new name for an existing method; exclusion: an operation that forms a
When the associated visit method is called, its implementation is chosen based on both the dynamic type of the visitor and the static type of the element, as known from within the implementation of the accept method, which is the same as the dynamic type of the element. (As a bonus, if the visitor can't handle an argument of the given element's ...
Simple Logging Facade for Java (SLF4J) provides a Java logging API by means of a simple facade pattern.The underlying logging backend is determined at runtime by adding the desired binding to the classpath and may be the standard Sun Java logging package java.util.logging, [2] Log4j, Reload4j, Logback [3] or tinylog.
