Eclipse følger dig hele vejen

”Har du tænkt på at skifte til et leverandøruafhængigt udviklingsmiljø? Det er gratis, og du får ét udviklingsmiljø, som du kan programmere alt fra Java, C, C++ og PHP til databaser og webserver i. Vi får dig til at se værdien af værktøjet, og se flere forskellige eksempler på brugen af Eclipse i praksis.

Kom og hør formanden for eclipse.dk, Tonny Madsen, Direktør, RCP Kompaniet fortælle om Eclipse.

Eclipse er component-baseret, og du får indsigt i hvordan du sammensætter Eclipse til netop dine behov.”

Basically…

We need an architecture that supports distributed development over a large number of autonomous development groups

We need a component concept where components are loosely coupled and can be started (and stopped) independently

We need a way to describe external interfaces of components and dependencies between components

We need a way to only start the components as they are needed – also known as late activation

We need all this to work over multiple generations of components

PR0017 - 2009-09-29

12

Eclipse Architecture

Goals for the Eclipse architecture Be able to host any number of 3rd party applications Scalability in terms of size and complexity of hosted applications Alignment with native UI look-n-feel

Flexible architecture, structured around Plug-ins – the basic unit of functionality Extension points – the defined interfaces between plug-ins

This architecture allows for Implementation of 3rd party applications on top of the basic platform

(Eclipse RCP) Additional tools to be integrated in the platform Integrated tools to be further extended

The Basic RCP Components

In the Eclipse, everything is a plug-in including the run-time platform itself It is a small kernel that represents the base of the platform Built on top of OSGi

All subsystems built on the run-time platform follows the rules of plug-ins: They are plug-ins themselves

RCP includes: Component Management Resources Management Preferences Workbench (include SWT and JFace)

RCP does not include functionality that are not commonly needed: Update Help This can be included from the Eclipse platform

Organizing the Platform

The software of an Eclipse system is based on the following terms: Plug-ins – a plug-in is the basic unit of software Fragments – a fragment is an add-on to an existing plug-in with

additional functionality Features – a feature is a number of plug-ins that is distributed and

updated as a whole Applications – an application is a Java class that implements a specific

interface and is declared as such in the plug-in Products – a product is a set of features or plug-ins along with the

appropriate branding

PR0017 - 2009-09-29

17

Extension Points

Describe additional functionality that could be integrated with the platform External tools extend the platform to bring specific functionality Java Development Tooling (JDT) and Plug-in Development Environment (PDE)

are external tools integrated with the platform Extension points are used to

Add an implementation for a generic feature Extend the workbench Extend common object factory

Advantages: Allows for late load and startup of plug-ins Provides a common “registry” for most extensions like views, perspectives,

commands, etc Disadvantages:

Makes it harder to understand flow of control ID Hell!

Extension points may have corresponding API interface Describes what should be provided in the extension

Business Requirements

Provide process support Show/hold all functionality and information in one place

Seamlessly integration between the functional areas Data re-use

Integration Support Integration with existing applications such as 3270, browser based

and native Windows (word, excel etc.) External peripherals High usability

Follow the OS Standard keyboard navigation, icon, help, drag & drop

High performance

PR0017 - 2009-09-29

28

IT/Project Requirements

Parallel development No hard decencies to the other projects Different release dates for the a functional area (projects) Different dependencies to the back-end Nordea is a bank, - not a major IT product company Mature and well tested framework Go out and buy the funtionality

The Process

Project started in 2006 with an evaluation Several different frameworks were evaluated

Portal based Eclipse RCP NetBeans Platform

Several Eclipse RCP frameworks were evaluated Major part of the evaluation was a fully functional prototype

Access to ”real” data Divided into functional areas as a number of independent plug-ins
