Description:

Understanding other people's code or your own code in complex systems is a challenging problem in software development. This plugin supports developers in learning the dependencies and couplings in object oriented systems. Three major plugin-functions can be used:

class cloud diagram
graphical navigation between dependent classes
creation of UML diagrams

The class cloud diagram should be used as a first step when trying to understand an object oriented system. It shows all project classes in a single diagram as a cloud, very similar to tag clouds known from web-applications. Some of the most important classes can such be found by using the class cloud to be further investigated by using the graphical navigator or the source code. Graphical navigation can be used to find aCnd understand all dependencies (using classes, used classes, extending classes and extended classes of some subject class). As soon as the developer has understood which classes interact in which way, UML diagrams should be created that condense this knowledge. Though it is really helpful to have at least some UML diagrams, many software systems are not documented well or the existing diagrams are totally outdated. This plugin helps to create static class diagrams that always can be kept in sync with the current state of a system. The new functions can be accessed by a new menu item in the Analyze menu of the main menu bar (Analyze Class Cloud) and two new menu items in the project view and editor popup menus (Show in Graphical Navigator and Add to UML Diagram).

added: undo in diagram creation step editor

Version 1.22(_8):

changed: class cloud and graphical navigator graphs are saved with same writer as used for UML diagrams so always a good image quality is achieved

added: added reset view button to class cloud toolbar
changed: added new settings for class cloud and rearranged settings dialog
changed: no new layout will be computed automatically when removing classes from UML diagrams

changed: UML diagrams will now be updated for rename class/package and move class/package refactorings and for corresponding undo operations of rename and move refactorings

Version 1.16:

fixed: some minor bugs
changed: suggested diagram name for new UML diagrams is now based on selected classes

Version 1.15:

fixed: in some cases on slow machines, the graphical navigator did not repaint node labels at the end of an animation
fixed: graphical navigator did not always repaint properly on first opening tool window
added: new action "jump to graphical navigator" jumps directly to chosen class, shortcut is "ctrl alt shift G"
added: graphical navigator draws direct cyclic dependencies between classes in red. Can be disabled in settings dialog.

Version 1.14:

fixed: saved diagrams could only be loaded explicitely, if at least one diagram existed
added: UML diagram node popup menu items for connecting nodes with more control
added: UML diagram edge popup menu items for removing multiple edges at once
changed: reorganized UML diagram node popup menu
added: if a package is added to a UML diagram, all contained classes are added instead
changed: if an openend diagram already exists, the user will be asked whether to replace, skip or rename the diagram instead of always renaming it
fixed: rename button in UML diagram tool window toolbar throwed exception, if no diagram existed
fixed: "add to new diagram" menu item throwed exception, if IDEA does not use JDK 6 (for example on Macs)
added: "add to new diagram" menu item and "show in graphical navigator" menu item are now also accessible from editor tab popup menu

Version 1.13:

Anonymous Rated: 2009-02-10 00:32:22	Great plugin. I have a suggestion though: diagrams would be more informative if associations and aggregations were labeled in some way. E.g. the name of the property could be used if the relationship is an aggregation. .
palob Rated: 2009-02-09 14:52:28	This is great plugin! I am currently analysing unknown project and it helps me a lot. One feature I miss is possibility to add a Note that can be attached to a class. That would help me to put gained knowledge into diagram or event to create the documentation :-) .

Anonymous Rated: 2009-02-06 18:55:17	The tool I looked for plenty of years. Wonderful. Nice enhancement would be: Show the classes inside of a box representing the Idea Module the class comes from. .
Boomah Rated: noRate 2009-02-05 11:22:52	Hi. This looks good but whenever I expand the graphical navigator or uml diagram the window comes out half the way, my CPU shoots through the roof and idea hangs for 10 seconds and then it works fine. This is on a small project using sun update 10 on ubuntu. .
AlexLin Rated: noRate 2009-01-14 05:50:05	When some classes are referenced by some jsp, JspClass will be added into UML Diagram but it is not able to be removed. There are some buttons with odd name in Print Options and Print Preview. .

AlexLin Rated: noRate 2008-12-16 08:09:41	Now it is not compatible with Max OS X because it use "java/awt/geom/Path2D$Float" which is in JDK 1.6. .
Anonymous Rated: noRate 2008-12-04 00:48:42	Has anyone had issues in which showing the Graphical Navigator ONLY shows a class Foo, even if Foo uses Bar. Every class in my project just comes up in the window by itself when I try to use this plugin (w/ 8.0). Also, if I attempt to Analyze Class Cloud, I get an error stating "Selected scope does not contain any classes." Any tips? Thanks! .
Anonymous Rated: noRate 2008-10-29 11:59:12	The class cloud analysis may need a lot of memory in large projects. If You get an error message like "There's not enough memory to perform the requested operation..", You should increase the maximum heap size for IDEA (see idea.bat on windows). .

FraG Rated: noRate 2008-10-24 13:05:56	I am really stupid: I will just use "-target 1.5" to recompile all classes for JDK 5 based Mac OS X Idea installations. .
FraG Rated: noRate 2008-10-23 12:11:26	I would recompile the plugin using JDK 5 but I found no way how to do it! How do I compile a plugin that needs IDEA 7 using JDK 5 without using a MAC? On Windows IDEA 7 does not run under JDK 5. .
Anonymous Rated: 2008-10-23 05:47:46	Very slick. Can you build it against JDK 5. Intellij 7.0.4 doesn't run reliably on 6 and your plugin won't run if Intellij's running under JDK 5 (Unsupported class version error), since it seems to have been built on JDK 6. thx .

merlin@ctco.lv Rated: noRate 2008-09-11 19:05:21	Good work :) Do you have any plan for code analysis? For example: you could draw in red (as bad practice) classes with the cycle dependencies .
constv Rated: 2008-09-11 18:50:05	Also, it would be great to be able to select a whole package in the Project or packages view, right-click, and perform an operation on the package or packages, For example, create a UML class diagram that would include all the classes in the package. It seems that right now, the only way is to explicitly highlight the classes under the package and add them to the UML diagram. .
constv Rated: 2008-09-11 18:44:19	Great plug-in. Hope to see it updated to work with Diana (IDEA v. 8.x) soon. .
FraG Rated: noRate 2008-09-11 02:37:10	merlin@ctco.lv: thanks - as you can see in the change notes, I implemented one of your suggested features. .
merlin@ctco.lv Rated: noRate 2008-09-10 11:58:40	Another option. :) When you open the window - Graphical Navigator and no any class has been added to this window instead of showing blank window you could open it with the current class which is already open in java code editor. .
merlin@ctco.lv Rated: 2008-09-10 11:53:33	It's really nice plug-ig. I like it. May I suggest add some additional feature? :) When you in a window - Graphical Navigation it would be good to have possibility quickly navigate to class (for example using short cut: Ctrl + N, select class and open it in the window Graphical Navigation). .
