OTcl
OTcl usually refers to an Object-oriented programming, object oriented extension of Tcl created by David Wetherall at MIT (hence the name OTcl—short for MIT Object Tcl). It is used in Ns (simulator), network simulator (NS-2) and usually run under Unix environment.Eitan Altman and Tania JiménezNS Simulator for beginners Lecture notes, 2003-2004, Univ. de Los Andres, Merida, Venezuela and ESSI, Sophia-Antipolis, France This was later extended into XOTcl. OTcl may also refer to the unrelated IXI Object Tcl extension by Dean Sheenan. These object Tcl extensions predate the more popular incr Tcl. Syntax Introduction The reserved word ''Class'' is used to represent class and method of class are declared using word ''instproc''. The variable ''self'' is pointer to the class it is used in and is equivalent to variable ''this'' of C++/Java. The keyword ''-superclass'' is used for defining hierarchy. For example, ''Class Son -superclass Father'' means that ''class Son'' inherits from '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XOTcl
XOTcl is an object-oriented extension for the Tcl, Tool Command Language created by Gustaf Neumann and Uwe Zdun. It is a derivative of MIT OTcl. XOTcl is based on a dynamic object system with metaclasses which as influenced by CLOS. Class (computer science), Class and Method (computer science), method definitions are completely dynamic. XOTcl provides language support for Design pattern (computer science), design patterns via filters and Decorator pattern, decorator mixins.

Incr Tcl
incr Tcl (commonly stylised as ''ncr Tcl/nowiki>'', and often abbreviated to ''itcl'') is a set of object-oriented extensions for the Tcl programming language. It is widely used among the Tcl community, and is generally regarded as industrial strength . Its name is a pun on "C++". Itcl implementations exist as both a package that may be dynamically loaded by a Tcl application, as well as an independent standalone language with its own interpreter. Overview Features Namespace support Itcl allows namespaces to be used for organizing commands and variables. Example: package require Itcl itcl::class Toaster itcl::class SmartToaster set toaster martToaster #auto$toaster toast 2 C code integration Itcl (like Tcl) has built-in support for the integration of C code into Itcl classes. Licensing Itcl follows the same copyright restrictions as Tcl/Tk. You can use, copy, modify and even redistribute this software without any written agreement or royalty, pr ...

Ns (simulator)
ns (from network simulator) is a name for a series of discrete event network simulators, specifically ns-1, ns-2, and ns-3. All are discrete-event computer network simulators, primarily used in research and teaching. History ns-1 The first version of ns, known as ns-1, was developed at Lawrence Berkeley National Laboratory (LBNL) in the 1995-97 timeframe by Steve McCanne, Sally Floyd, Kevin Fall, and other contributors. This was known as the LBNL Network Simulator, and derived in 1989 from an earlier simulator known as REAL by S. Keshav. ns-2 Ns-2 began as a revision of ns-1. From 1997 to 2000, ns development was supported by DARPA through the VINT project at LBL, Xerox PARC, UCB, and USC/ISI. In 2000, ns-2 development was supported through DARPA with SAMAN and through NSF with CONSER, both at USC/ISI, in collaboration with other researchers including ACIRI. Features of NS2 1. It is a discrete event simulator for networking research. 2. It provides substantial su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as ''methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with imper ...

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (Berkeley Software Distribution, BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris (operating system), Solaris), Hewlett-Packard, HP/Hewlett Packard Enterprise, HPE (HP-UX), and IBM (IBM AIX, AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are chara ...

Tk (programming Language)
Tk is a free and open-source, cross-platform widget toolkit that provides a library of basic elements of GUI widgets for building a graphical user interface (GUI) in many programming languages. Tk provides a number of widgets commonly needed to develop desktop applications, such as button, menu, canvas, text, frame, label, etc. Tk has been ported to run on most flavors of Linux, Mac OS, Unix, and Microsoft Windows. Like Tcl, Tk supports Unicode within the Basic Multilingual Plane, but it has not yet been extended to handle the current extended full Unicode (e.g., UTF-16 from UCS-2 that Tk supports). Tk was designed to be extended, and a wide range of extensions are available that offer new widgets or other capabilities. Since Tcl/Tk 8, it offers "native look and feel" (for instance, menus and buttons are displayed in the manner of "native" software for any given platform). Highlights of version 8.5 include a new theming engine, originally called Tk Tile, but it is now gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
