Tutorial by Topics: classes

Using Java, developers have the ability to define a class within another class. Such a class is called a Nested Class. Nested Classes are called Inner Classes if they were declared as non-static, if not, they are simply called Static Nested Classes. This page is to document and provide details with ...

A class groups different functions, methods, variables, and properties, which are called its members. A class encapsulates the members, which can be accessed by an instance of the class, called an object. Classes are extremely useful for the programmer, as they make the task convenient and fast, wit...

The class of a data-object determines which functions will process its contents. The class-attribute is a character vector, and objects can have zero, one or more classes. If there is no class-attribute, there will still be an implicit class determined by an object's mode. The class can be inspected...

A storage class is used to set the scope of a variable or function. By knowing the storage class of a variable, we can determine the life-time of that variable during the run-time of the program. [auto|register|static|extern] <Data type> <Variable name>[ = <Value>]; [s...

To avoid serialization problems, particularly in distributed environments (e.g. Apache Spark), it is a best practice to implement the Serializable trait for type class instances.

As you build adaptive apps, keep in mind the limitations of size classes: they are generalizations, not specific guides for exact pixel sizes or devices. Never attempt to determine what device your app is running on, or whether it's in a split-screen mode, based on the size classes. Instead, make...

class Foo { } // inherits from Object class Bar: Foo { } // Bar is a Foo too Foo f = new Foo(); // instantiate new objects on the heap See the specification, browse a book chapter on classes, inheritance and play interactively.

Qt provides its own template container classes. They are all implicitly shared. They provide two kinds of iterators (Java style and STL style.) Qt sequential containers include: QVector, QList, QLinkedList, QStack, QQueue. Qt associative containers include: QMap, QMultiMap, QHash, QMultiHash, QS...

For more details ( Size Classes and Adaptivity through Storyboard) of using auto layout for adaptivity in iOS, we can follow the apple developer site link. We can also add constraints Programatically using Visual Format Language as described here at apple developer site.

\documentclass{...} This topic aims to explain the different types of document and their specificities. A good way to organize it would be 1 example per type

In this topic I would like to mention all possible global variables which can be used in Apex code. Like [UserInfo Class][1]. I suggest we just list a global classes/variables and links. If you know about a global class/variable but can't find a documentation, please provide as much informati...

In order to use custom tags in JSP,we used to have TLD files,along with a Java class to define the custom tags but post JSP 2.0 specs,the same can be achieved,without the need for any Source code files,making it easy to maintain and it can also be created by someone with basic knowledge of JSP tags ...

The easiest way to create a RESTful API in Grails is to expose a domain class as a REST resource. This can be done by adding the grails.rest.Resource transformation to any domain class.
