Perl is a great language for throw-away programming hacking quick solutions to urgent tasks. It can also be a great language for developing large, robust and reusable solutions to real-life problems. The object-oriented techniques taught in this book will help you write cleaner, more readable and more maintainable Perl programs. Whether you're a complete newcomer to object orientation, a refugee from C ++, or just another Perl hacker looking to extend your skills, this book will take you from first principles to practical techniques, and on to the deepest mysteries of object orientation. What's inside : building objects from hashes, arrays, scalars, pseudo hashes, subroutines, regular expressions, or typeglobs ; mastering encapsulation, inheritance, and polymorphism ; advanced topics : operator overloading, tied variables, generic programming, multiple dispatch, and persistence ; practical examples : databases, pattern matching, source code manipulation, multiprocessing, encryption, search trees, filtering 1/0 streams, debugging ; transition guides from C ++, Java, Eiffel, and Smalltalk.
