Course Description:

'' Perl 5 is a highly successfully high level programming language. This short course discusses Perl’s object orientation features.
To the uninitiated Perl does not at first appear to have many OO features. However most modules are written with an OO interface these days, and today’s programmers expect languages to be capable of OO. Perl has these features, although the techniques to use them may be different from other popular languages. This course not only describes the basic syntax and implementation details, it discusses the techniques required to use them effectively.

Practical exercises are used to consolidate the information learned during the lecture sessions and demonstrations. These will demonstrate many of the differences between alternative implementations.



Prerequisites
Before attending this course delegates must have the following as pre-requisites:

Existing Perl 5 developers who wish to write and use object orientation. Support staff with Perl 5 experience who intend to support Perl classes and code that uses Perl objects.
Delegates must have recent day-to-day experience of Perl, preferably to the level in the QA “Perl Programming�course. No previous OO experience is necessary.




Delegates will learn how to
On completion of this course, delegates will be able to:

Explain the basic concepts and terminology of object-oriented programming
Use common objects and references types
Create, initialise, and destroy objects in a Perl application
Store class structures and objects for later reuse
Derive new Perl classes from existing classes
Create self-contained classes in a Perl application
Understand different forms of Perl Encapsulation, and choose between them
Use advanced features of Perl 5 object orientation.
