Design Patterns for Concurrent Objects

Design Patterns for Concurrent Objects

Design Patterns are recipes for writing maintainable and reusable object-oriented software.  This lecture presents several patterns used for distributed and multithreaded programming.

The lecture targets programmers interested in making their software more generic and reusable, especially those working on a multithreaded application.  Also programmers interested in Event-Handling Techniques may benefit from it.

Basic knowledge of threads, object oriented programming (classes, objects, methods, inheritance) is required.  Additional knowledge of the classical Design Patterns might help but is not required.
