Intended audience: C++ programmers

This course focuses on the new ANSI C++ Standard Template Library (STL), a set of reusable containers and algorithms.

The STL design is different from that of traditional container libraries, and maintains a clean separation between algorithms and containers. This philosophy can be applied to many other library domains, and may change the way that C++ libraries are designed and implemented.

STL users in the C++ community seem to enjoy their new-found power, but some programmers are concerned that STL can be accidentally misused and cannot be used effectively in a multi-threaded environment. The course addresses these issues and also shows how STL can be enhanced in a non-intrusive way.

The course is comprised of the following sections:

• the background, philosophy, and operation of STL
  
• making STL easier to use
  
• using STL in a multi-threaded environment
  
• adding persistence to STL

Intended audience: Developers and system architects who are considering using OLE and COM as an object model for building distributed applications. The course assumes a working knowledge of C++.

Network OLE (formerly known as Distributed COM or DCOM) is a lightweight object model that allows objects to be transparently distributed across heterogeneous platforms and networks. While the initial release is bundled with Windows NT, support for most major platforms, including most UNIX variants, is currently in development.

This course gives a detailed look at the programming techniques used to implement COM objects that support transparent distribution and language-independent interoperability. The topics covered are:

COM as a Binary Standard

Interfaces as binary firewalls

The C++ Binding for COM

IUnknown and the Laws of COM

Packaging and Advertising COM Servers

Class Objects and Servers

The Service Control Manager (SCM)

COM Interface Definition Language (IDL)

IDL Basics

Building type libraries using IDL

Standard Marshaling Architecture

The Standard Marshaler

Building Proxy/Stub pairs in IDL

Custom Marshaling

Marshaling via private subcontracts

Marshaling by value

Implementing Smart Proxies

Network OLE Specifics

OXIDs/OIDs/IPIDs - Identifying Servers, Objects, and Interfaces

Object References on the Wire

OLE on UNIX

COM Threading and Concurrency Models

Apartment Model Threading - Why and How

Freethreaded COM - Performance and Constraints

Connection Points

Bi-directional Contracts

Exposing and discovering Outbound Interfaces

Don Box has been working in networking and distributed object systems since 1989. He is currently chronicling the COM lifestyle in book form and writes a regular column on OLE in both the C++ Report and Microsoft Systems Journal. He is active as a consultant on COM-related projects and regularly gives seminars on OLE and COM.

Intended Audience: Software developers and technical managers. The level of this course is intermediate to advanced; no previous exposure to patterns is necessary.

A pattern gives a solution schema to a recurring design problem in software development. While patterns have been gaining considerable attention during the last few years, previous efforts concentrated on low-level patterns (idioms) and mid-level patterns (design patterns).

The course will discuss patterns at the level of overall software architectures. It will present a system of patterns for software architecture that combines the high level patterns with an enriched set of lower-level patterns, and organizes them into a cross-referenced catalog.

The course will provide in-depth explanation of the notion of patterns, presenting several patterns at different levels of granularity. Example patterns are:

• Broker
  
• Layers
  
• Blackboard
  
• Model-View-Controller
  
• Publisher-Subscriber
  
• Client-Dispatcher-Server
  
• Counted Pointer
  

Participants will be provided with preprints of full pattern descriptions using a system of interrelated patterns in a practical example.

Dr. Hans Rohnert works for the Siemens Corporate R&D labs in Munich, Germany. He is co-author of an upcoming book, Pattern-Oriented Software-Architecture - A System of Patterns. He studied at the University of Saarland and the International Computer Science Institute at UC Berkeley. His research interests include patterns, object-oriented programming, combinatorial algorithms, and data structures.

Intended Audience: System analysts, architects, and programmers involved in management of networks, systems, and services. Participants should know either CMIP or SNMP. Knowledge about CORBA architecture and OMG Interface Definition Language (IDL) will be helpful.

After this course, participants will be able to apply CORBA and object services for network and system management applications.

This course is based on current draft specification of Joint Inter-Domain Management Task Force (XoJIDM) sponspored by X/Open and Network Management Forum. The Inter-Domain Management specification is divided into two parts: specification translation and interaction translation.

This course will cover:

• Overview and Status of XoJIDM Activities
  
• Overview of CORBA and IDL
  
• Issues in Inter-Domain Management
  
• Specification Translation Schemes
  
  • Mapping of ASN.1 Types to CORBA-IDL Types
    
  • Mapping of GDMO Templates to CORBA-IDL Interfaces and Operations
    
  • Mapping of SNMPv2 MIB to CORBA-IDL Types and Interfaces
• Issues related to Interaction Translation in OSI System Management
  
  • Mapping of Names
    
  • Mapping of LifeCycle Service
    
  • Mapping of Events and support for Filtering
• Gateway between ORB and CMIP/SNMP network Management Agent
• Summary and Discussion

After this course, participants will be able to apply CORBA and object services for network and system management applications.

Subrata Mazumdar currently works at Bell Laboratories, Lucent Techonologies. Previously, he was with IBM T.J. Watson Research Center where he developed the architecture and prototype of a protocol-independent network management agent, a CORBA-based OSI system management agent, and designed and implemented the prototype of a CORBA-based TINA-C Distributed Processing Environment for multi-media services.

Intended Audience: Participants with some programming experience who would benefit from a powerful, easy-to-use, very high level object-oriented programming language.

Python is an interpreted high level object-oriented programming language, combining remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing.

A large collection of existing modules is available for system programming, GUI development, database management, scientific computing, building WWW applications, distributed computing, and more. New modules are easily written in Python, C, C++, or other languages that can interface with C. Python may also be used as an extension language for applications that need a programmable interface. Python is highly portable: it runs on UNIX, DOS, Windows, Macintosh, OS/2, Amiga, and other platforms.

This course will provide a basic introduction to Python, including:

• Python Basics
  • Using the Python interpreter interactively,
    
  • Python expressions and control statements,
    
  • Using Python modules and high-level data types,
    
  • Creating Python scripts,
    
  • Standard Python object protocols,
    
  • Writing Python functions,
    
  • Creating Python Modules,
    
  • Using documentation strings to make objects self-documenting,
    
  • Overview of pre-existing modules

• Object-Oriented Programming in Python
  • Class definition,
  • Special methods for implementing standard protocols:
    
    • Numeric types,
    • Sequence types,
    • Mapping types,
    • Callable objects,
    • Overriding standard method attribute lookup,
  • Overview of defining new object types using C or C++ extension modules.

Jim Fulton is a consultant and software engineer with several years experience building systems using a variety of object-oriented languages. He has served on the ANSI Smalltalk committee and is currently a member of the Python Software Activity steering committee. Mr. Fulton holds a BS and MS from Case Western Reserve University, and an MS from George Mason University.

Intended audience: Software developers familiar with general object-oriented design and programming techniques (design patterns, modularity, and information hiding), fundamental OO programming language features (classes, inheritance, dynamic binding, and parameterized types), basic systems programming concepts (process/thread management, synchronization, and interprocess communication), and networking terminology (client/server architectures and TCP/IP).

This course examines and evaluates a suite of OO design patterns that help to alleviate the complexity of developing concurrrent, parallel, and distributed object-oriented software. These patterns (and the framework components that implement them) have been used successfully on major OO communication software projects to build telecommunication switch management applications, network management for large-scale global personal communication systems, and electronic medical imaging systems.

The course illustrates by example how to significantly simplify and enhance the development of software that effectively utilizes concurrency and network services via the use of:

• Object-oriented design techniques - design patterns, layered modularity, and information hiding
  

• C++ language features - abstract classes, inheritance, dynamic binding, and parameterized types
  

• Tools - object-oriented communication frameworks (such as ACE) and object request brokers (ORBs)
  

• Advanced operating system mechanisms - event demultiplexing, multi-threading, multi-processing, and explicit dynamic linking
  

• Emerging standards for distributed object computing - OMG CORBA and Network OLE/COM
  

The course examines patterns and C++ code abstracted from production distributed electronic medical imaging and telecommunication systems to illustrate key points in the examples.

Doug Schmidt is an assistant professor of Computer Science at Washington University in St. Louis, Missouri. His research focuses on design patterns, implementation, and experimental analysis of object-oriented techniques for developing high-performance, distributed communication systems on parallel processing platforms that run over high-speed networks.
