FAQPage Schema

How do I define classes in ObjectScript for InterSystems IRIS?▼

To define classes in ObjectScript, you use specific syntax to declare the class block, then add parameters, properties, and methods. This establishes the foundational structure for object-oriented programming within InterSystems IRIS.

What is the difference between instance methods and class methods in ObjectScript?▼

Instance methods in ObjectScript operate on a specific instantiated object and its properties, while class methods are invoked directly on the class definition itself without needing an instantiated object to execute.

How does inheritance work in InterSystems IRIS class programming?▼

Inheritance in InterSystems IRIS allows a new class to derive properties and methods from an existing parent class. This mechanism promotes code reuse and establishes hierarchical relationships within your object-oriented application structure.

Can I use object-oriented programming paradigms with ObjectScript?▼

Yes, ObjectScript fully supports object-oriented programming paradigms by enabling you to work with objects, define properties, implement instance and class methods, set parameters, and utilize class inheritance within the InterSystems ecosystem.

What are parameters in an InterSystems IRIS class definition?▼

Parameters in an InterSystems IRIS class definition are compile-time constants that provide configuration values for the class. They are distinct from properties, which hold runtime data values specific to instantiated objects.
