InterSystems: The power behind what matters   

Describes the structure of a class definition.
In InterSystems IRIS, a class can include familiar class elements such as properties, methods, and parameters (known as constants in other class languages). It can also include items not usually defined in classes, including triggers, queries, and indexes.
A class definition has the following structure:
Import import_ppackage_list  
Include include_code  
IncludeGenerator include_generator_code  

/// description 
Class package.shortclassname Extends superclass_list [ class_keyword_list ]
