Class

The Class definition declares a class type. Classes can contain imports, constants, variables, member variables, functions, methods, and other classes (called inner classes). A function with the same name as a class (if any) is called a constructor. A constructor is called when a new instance of a class is created using a new operator.

Inside a class an ordinary function or variable definition declares a method and a member variables. However when prefix with ``static´´ they declare function and variable instead. Body of function or variable initialization is a static region, from which no instance bound entities may be referred.

Class may extend one other class, referred to with a dotted name. xxx.

Class may implement one or more interfaces, referred to with dotted names. xxx.

Some class methods have a special meaning. See Class customization.
