Java Programming : Eclipse IDE

Eclipse is an open-source, platform-independent software framework for delivering what the project calls "rich-client applications", as opposed to "thin client" browser-based applications. So far this framework has typically been used to develop Integrated Development Environments (IDEs), such as the Java IDE called Java Development Toolkit (JDT) and compiler (ECJ) that comes as part of Eclipse (and which are also used to develop Eclipse itself). However, it can be used for other types of client application as well, such as the BitTorrent client Azureus.

Eclipse is also a community of users, constantly extending the covered application areas. An example is the recently created Eclipse Modeling Project, covering most areas of Model Driven Engineering.

Eclipse was originally developed by IBM as the successor to its VisualAge family of tools. Eclipse is now managed by the Eclipse Foundation, an independent not-for-profit consortium of software industry vendors. Many software tool vendors have embraced Eclipse as a future framework for their IDEs.

Architecture

The basis for Eclipse is the Rich Client Platform (RCP). The following components constitute the rich client platform:

    * Core platform - boot Eclipse, run plugins
    * OSGi - a standard bundling framework
    * the Standard Widget Toolkit (SWT) - a portable widget toolkit
    * JFace - file buffers, text handling, text editors
    * The Eclipse Workbench - views, editors, perspectives, wizards

Eclipse's widgets are implemented by a widget toolkit for Java called SWT, unlike most Java applications, which use the Java standard Abstract Window Toolkit (AWT) or Swing. Eclipse's user interface also leverages an intermediate GUI layer called JFace, which simplifies the construction of applications based on SWT.

Eclipse employs plugins in order to provide all of its functionality on top of (and including) the rich client platform, in contrast to some other IDEs where functionality is typically hard coded. This plugin mechanism is a lightweight software componentry framework. In addition to allowing Eclipse to be extended using other programming languages such as C and Python, the plugin framework allows Eclipse to work with typesetting languages like LaTeX, networking applications such as telnet and database management systems. The plugin architecture supports writing any desired extension to the environment, such as for configuration management. Java and CVS support is provided in the Eclipse SDK. It does not have to be used solely to support other programming languages.

The Eclipse SDK includes the Eclipse Java Development Tools, offering an IDE with a built-in incremental Java compiler and a full model of the Java source files. This allows for advanced refactoring techniques and code analysis. The IDE also makes use of a workspace, in this case a set of metadata over a flat filespace allowing external file modifications as long as the corresponding workspace "resource" is refreshed afterwards.
