Fra forretningside til bundlinie:
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

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

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
