The Java Reverse Engineering is available in the extra plugins of Papyrus. It allows Java files or packages to be reverse-engineered into a Papyrus class diagram.
Contents
Installation Instructions
Java Reverse Engineering is available as a Papyrus extra plugin.
You can install it by using the Papyrus update site corresponding to your Papyrus version:
Or you can use the nightly build update site (paste following URL in eclipse update site):
Then :
- Unselect 'Group item by category'
- Select ' Papyrus Java Reverse (Incubation)'
- Finish
How to use Reverse
Using Command
Reverse-engineer a Java class
A Java class can be reverse-engineered into a Papyrus class diagram:
- open the class diagram,
- select a Java package from a project
- click the Reverse button
A UML class has been created in Model Explorer. You can now add it into your diagram. Note that all associated classes have also been added to the model.
Reverse-engineer a package
A Java package (and all classes included) can be reverse-engineered into a Papyrus class diagram:
- open the class diagram,
- select a Java package from a project,
- click the Reverse button
Packages and classes have been created in Model Explorer. Your can now add them to your diagram. Note that all associated classes have also been added to the model.
Reverse-engineering settings
By default, a package named "generated" is created for reverse-engineering. You can choose another package name on the options menu.
This options menu allows to:
- change the default package of the reverse-engineering,
- add or remove search path. The reverse generator search existing UML classes and regenerate them.
- add or remove creation path. The reverse generator search on existing Java classes to generate a UML class. Useful for creating Java imports (e.g.: String, Integer).
Using Drag & Drop
You can reverse-engineer a class or a package just by dragging & dropping it on a Papyrus diagram:
- Drag one or more classes and/or packages,
- Drop the selection into an open diagram.
A settings dialog is opened. You can modify settings (please see Reverse settings). In case when you're reversing by using drag & drop way, you can also choose to display model, packages, and classes / interfaces / enumerations into the papyrus diagram. To enable displaying, just click into the check-boxes:
When you click on the OK button, your components are displayed in the Papyrus diagram. Note: while all selected components are reversed-engineered, only components which are in selection, but not in the Papyrus diagram are displayed.
Change default reverse-engineering settings
The Java code reverse-engineering plugin allows you to change default settings on eclipse preferences:
- Open Eclipse Preferences,
- Search for the Papyrus section,
- Choose Java Code Reverse sub-section
In this preferences page, you can change:
- default search path values,
- default creation path values.
Note that there are default values; if you have changed these values for a project, your changes are saved, and default values are not used.
