Object technology appears to be a bewildering field in constant turmoil. But the core concepts of object-oriented programming endure as a paradigm for advanced programming methodology. By analyzing and comparing three different object-oriented languages, Objects Unencapsulated probes the core of object technology to examine how various language features affect software productivity.

Objects Unencapsulated examines and compares the strengths and weaknesses of Java, Eiffel, and C++. Topics covered include:

  • Objects, classes, modules, and types.
  • Features and interfaces.
  • Inheritance and genericity.
  • Concurrency and garbage collection.

Grounded by his belief that true innovation demands constant re-evaluation, Ian Joyner strips away the superficial distinctions between these languages to find the essence of object-oriented programming. He explains the facts behind the many controversies that an object-oriented practitioner constantly faces. By explaining some essential theory in practical terms, Objects Unencapsulated exposes the principles of the object-oriented paradigm.
