Web Resources:

Content:

1. Syllabus
   Describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.

2. MTMU Help Sessions:

   • Friday, 4/28 at 10:30am in CST 4-201 (Project #4 help from 9:00am to 10:30am)
   • Friday, 5/5 at 9:00am in CST 4-201

3. Projects:

   Project #4, Project4HelpS17
   Remote Code Publisher

   Project4HelpS17
   C++\CLI WPF client that sends and gets messages using native C++ mock channel.
   C# WPF client with C++\CLI shim that sends and gets messages using native C++ mock channel.
   Also included are several diagrams that illustrate design ideas for Project #4 and some sample Socket code.

   Communication Channel, vsdx
   Diagrams for Peer-To-Peer communication, Client and Server communication processing, and Message structure

   Mock Channel Demo, vsdx
   Diagram illustrating native C++ to C++\CLI interoperation for the Project #4 GUI via a mock demo.

   Note:

   Project #4 is due Tuesday, May 02. We will charge 1 point per day for Wednesday and Thursday. After Thursday midnight the late fee increases to 5 points per day. Also, after midnight Thursday, we will not count bonus points. This is necessary since we have a very short time to complete grading projects and submit course grades.

4. Finishing STL Discussion

   STL Structure
   

   Lots of example code

   Removing Items from Containers

   STL Details

   STL Odds and Ends Presentation

   Calls to the operator() in Predicate Functors should not change the Functor's state .
   This is described in detail in the second required class text, "The C++ Standard Library", Second Edition, Josuttis,
   section 10.1.4, pages 483-486.

   Algorithms Demo

   std::shared_ptr<T>, std::unique_ptr<T>
   shared ownership and single owner pointers.

   XmlDocument uses std::shared_ptr<AbstractXmlElement>

5. Unit and Regression Testing

   FileSystem Unit Testing
   This demo illustrates the use of a light-weight test harness to support unit test and maintenance.

6. Design Principles:

   Review of design principles

7. C++11 - new features

   Herb Sutter's excellent and brief overview from his Blog

   C++11 additions

   C++11 concurrency
   Threads, locks, condition variables, async, futures, promises, packaged_tasks, and atomics

   C++11 BlockingQueue
   Uses condition variable and mutex to build a queue that blocks deQers when empty.

   Str strings
   Demonstrates move constructor and move assignment.

   Component Reference Counting
   Demonstrates variadic templates and functions.

   Symbol Table
   Illustrates how using aliases are a great design tool. Also demonstrates range-based for loops.

   Chrono Timer
   Uses Chrono library to build a high resolution timer precise to about 100 nanoseconds.

   Callable Objects
   Demonstrates lambdas and compares them to function pointers and functors.

   Singleton
   Uses atomic.

   Uniform Initialization
   Illustrates use of uniform initialization for user defined types and STL containers.

8. DLL Demo

   DLL Demo - implicit and explicit library loads
9. Other topics in the queue:
   • Packaging: Modules, Libraries, UIs, DLLs, and Programs
   • Managed C++ - C++/CLI, and its Syntax
   • Boltins, Veneers, and Constraints
   • Documenting OO Designs
   • Template Metaprogramming
10. Thinking about Software Design:
    Software Design
    Broad survey of ideas with examples
    Design Presentation
    Summarizes design issues for modules and classes.
    Design Guidelines
    Design rules and idioms that transcend Object Oriented Design.
