error while updating eclipse-20

The Eclipse platform has change listeners registered on the model objects and updates the user interface whenever you change relevant attributes.

Parts are user interface components which allow you to navigate and modify data.

Eclipse applications are based on some basic components, other components use them and provided extended functionality on top of them.

The Eclipse IDE can be viewed as a special Eclipse application with the focus on supporting software development.

Model elements can point to a class or to a static resource via a Uniform Resource Identifier (URI). Eclipse instantiates the referred objects or resources in most cases lazily. The corresponding object is created by the Eclipse framework.

For example, the classes for a part are instantiated when the part gets visible. Using the house/rooms metaphor from earlier, the class is responsible for defining the furnishings, the layout of the room and how the interactive objects behave. This runtime application model is dynamic, i.e., you can change the model objects and its attributes and these changes are reflected in your application.
