Perl tutoring5/4/2023 ![]() It means a method call can behave differently depending on the type of the object that calls it. Polymorphism means “ many forms” in Greek. A class that inherits from other class called subclass or derived class.A class that other classes inherit from is called base class or superclass.Inheritance enables you to reuse and extend existing classes without copy-n-paste the code or re-invent the wheel. Inheritance means one class inherits both attributes and methods from another class. It means the client of the object does not need to care about the internal logic of the object but still can use the object through its interfaces (methods). Through object, you can hide its complexity which is known as abstraction or encapsulation in object oriented programming. The following is the Product class in UML diagram. We typically use UML to model class including its attributes and methods. We often say an object is an instance of a class e.g., a phone is an instance of Product class. From the house blueprint you can build as many houses as you want. A house is an object but the house blueprint is a class. ClassĪ class is a blueprint or template of similar objects. You can change one of this information through methods that the phone object provides e.g., set_name, get_name, etc. A phone is a tangible object that has attributes: serial, name, price, etc. It is the data part of the object.Īn object can be anything tangible or intangible. Attributes or properties describe what information the object conveys.Actions or methods describe what it can do.Object is described in the following terms: ObjectĪn object is a single entity that combines both data and code. If you are not familiar with object-oriented programming, the following are the fundamental concepts to help you get started. You will learn how to create a simple Perl class and use it in other programs.īesides procedural programming, Perl also provides you with object-orient programming paradigm. Summary: in this tutorial, you will learn about Perl Object-Oriented Programming or Perl OOP.
