Understanding

View Java elements which are specific to Eclipse

Use EMF tools to detect Eclipse patterns

Highlight the model elements related to these patterns

ExistingPlug-in

Model of the Plug-in

Demo

Quality Analysis

Check plug-in development rules

Use EMF tools to detect problems in the model of the Plug-in

Store violations as Measurements into a SMM model

Inject violations into the Problem View

ExistingPlug-in

Model of the Plug-in

Model of the violations Problem View

Demo


Refactoring

Example:

Class must use UCI4J classes (yearly simultaneous release rule)

Detect all the references to 19 prohibited classes:• java.lang.Character• java.text.DateFormat• java.util.Calendar• etc…

Replace them by corresponding ICU4J classes
