Object-Oriented Perl: Mastering Getters, Setters, and Package Basics

Writing robust Perl code requires a solid understanding of how packages manage internal state. For developer efficiency and code reliability, relying on direct hash access inside objects can lead to fragile applications. This text-based course guides you through the core principles of object-oriented Perl, focusing on clean encapsulation and data integrity. You will start with the fundamental terminology of Perl packages, bless references, and standard object creation before moving on to robust accessor methods. By the end of this course, you will know how to control how data enters and leaves your objects, ensuring your applications remain stable and scalable. What you'll learn: Understand the core mechanics of Perl packages, namespaces, and the bless function; Build robust getter and setter methods to safely retrieve and update object attributes; Apply data validation inside setters to prevent invalid object states; Implement modern Perl practices including basic type checks and exception handling; Practice writing clean, maintainable object-oriented code through structured written exercises. This course begins with foundational definitions of Perl's object system and progresses logically through encapsulation strategies and modern validation workflows. It is designed for beginners who have a basic grasp of Perl variables and functions but are new to object-oriented programming in Perl.
