Data Transfer Object Design Pattern

This script is a sample implementation of the 'Null Object' design pattern. Roughly, the goal with Null objects is to provide an 'intelligent' replacement for the often used primitive data type None in Python or Null (or Null pointers) in other languages. These are used for many purposes...

This class implements the observer design pattern. Acting as a registration hub, it fires simple Events when requested.

Memento design pattern in python script allows you to cache instances based on what arguments are passed to them.

Class::Adapter is a Perl implementation of the "Adapter" Design Pattern. The Class::Adapter class is intended as an abstract base class for creating any sort of class or object that follows the Adapter pattern. What is an Adapter? The term Adapter refers to a "Design Pattern" of the same...

Data Grid Object can be used to display MySQL query results in HTML tables. It is based on another class originally written by Carlos Miguel Guevara.This version includes several enhancements:- The code no longer issues warnings with E_STRICT error reporting enabled- Produces XHTML compliant...

Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation [1]. This design pattern is also known as Cursor.Motivation: An example of an aggregate object is an instance of the List ADT. Consequently, an iterator can be used to traverse...

This script presents a design pattern that is highly reusable. Simple handlers implement one specific task from a complex set of tasks to be performed on an object. Such handlers can then be layered in a stack, in different combinations, together achieving complex processing of an object. New...

Intent: Ensures a class only has one instance and provide a global point of access to it [1].Motivation: It's important for some classes to have exactly one instance. For example, it can be desirable to have only a single instance of a GUI. With a MATLABdlT« GUIDE built GUI, the driver or main...

Progress is a utility used in a pipe to report progress of data transfer to standard error. Command-line arguments tells to specify how frequently to report, what character to use to report, and how much buffering to do. Whats New in This Release: - February 9, 2003 - progress 1.0 - Initial...

Metastorage is a PHP data access object generator compiler tool. Metastorage is an application that automatically generates code for an Object Oriented API to store, retrieve and manipulate the persistent objects of classes described in a high level data model definition. Metastorage provides...

WANPIPE S-series is a family of intelligent multi-protocol WAN and ADSL adapters that support data transfer rates up to 8Mbps. All WAN protocols supported by WANPIPE are implemented in firmware and run on the card. An advantage of an intelligent adapter is that it offloads the system CPU and...

Zebedee is a simple program to establish an encrypted, compressed "tunnel" for TCP/IP or UDP data transfer between two systems. This allows data from, for example, telnet, ftp and X sessions to be protected from snooping. You can also use compression, either with or without data encryption, to...

This code implements the policy design pattern in Python by using metaclasses and multiple inheritance.

Zebedee is a simple program to establish an encrypted, compressed “tunnel” for TCP/IP or UDP data transfer between two systems. This allows traffic such as telnet, ftp and X to be protected from snooping as well as potentially gaining performance over low-bandwidth networks from compression.

The Strategy Pattern is just one of many patterns defined by the "Gang of Four" that are commonly used in many other object-oriented programming languages.Now with Matlab 2008b we can define Interfaces and Abstract classes that can make use of many of these patterns. Not only is this good coding...

In software engineering, the active record pattern is a design pattern found in software that stores its data in relational databases. It was named by Martin Fowler in his book Patterns of Enterprise Application Architecture. The interface to such an object would include functions such as Insert,...

In multi-threaded and multi-process applications it is often desirable for data communications to follow the classic 'publish-subscribe' or 'observer' design pattern. RuffStuff is a C++ implementation of this pattern using BSD sockets.
