Likewise, a UML diagram can be created from existing code ("round-trip engineering"). Changes in the diagram are immediately reflected in the code and changes in the code are reflected in the diagram right away as well. This frees the developer to focus on the design and architecture of their system without worrying about the syntactical details of the programming language.Home page of Green UML.On-line DocumentationOff-line Documentation: In Eclipse, in the main top menu, go to Help/Help Contents and click on the Green Users Guide.To install the Green UML plug-in, please go to the Eclipse installation page.If you are new to UML class diagrams, it is highly recommended that you review the basics of UML first.Green UML Screen ShotQuick StartNote: Sometimes a change made directly in the Java code does not immediately show up in the diagram. It is recommended that after making changes directly to the code, whenswitching back to the diagram, right-click in any clear area of the diagram and select"Refresh Editor". This will insure that the diagram is properly synchronized with the code.Create a New DiagramImportant Note: Green UML will not work with classes in the default package! Inpractice, this is not really a restriction because you should always put all of your classesin packages and never have code in the default package.Create a New Blank DiagramIn the Package Explorer, right-click anywhere in the desired project and select "New/Other/Green UML Class Diagram"Create a New Diagram from an Existing Class or Interface -- creates a new classdiagram withNew class diagram with only one class/interface in it:Right-click the class orinterface in the Package Explorer and select "Green UML/Add to New ClassDiagram"New class diagram with the specified class/interface and its immediatesuperclass: Right-click the class or interface in the Package Explorer and select"Green UML/Incrementally Explore in New Class Diagram"Green UML will create an XXX.grn file in the root of the src folder (the defaultpackage location). To rename a class diagram, highlight it's *.grn file and go to the Eclipse main menu and select File/Rename or hit the F2 function key.Adding Classes and Interfaces to DiagramsCreate a New Class or Interface in the Diagram1.On the right side of the diagram, in the Palette, highlight either "Class" or"Interface".2.Move the mouse over to the desired location for the class on the diagram andleft-click to deposit a class or interface icon at that location.3.Fill out all the desired information in the pop-up dialog that appears.Green UML will automatically generate the appropriate Java file for your newclass or interface and will also auto-generate the code stubs for the class orinterface.Add an Existing Class or Interface to a DiagramTo add an existing class or interface to a diagram, be sure that the desired diagramis open and visible.Right-click the desired Java file in the Package Explorer and select Green UML/Add to Last Viewed Class DiagramModify a Class or Interface on a DiagramDouble-clicking on a class or interface will open its Java code file for editing.o Changing the visibility (public, private, protected, etc) of a class must be done via the code editor.Adding a method or field:1.Right-click the name of class or interface in the diagram to select the entireclass/interface2.Then select Add and then click Add Field or Add Method.3.Fill out the pop-dialog box with the appropriate specifications for the new field ormethod.Green UML will automatically generate a stub (signature but no code body) for anymethods and fields that are made.Editing an existing methodRight-click the method and select "Refactor/Change MethodSignature". This will bring up the dialog window to edit the signature of themethod.Adding Relationship Lines to a UML Class DiagramAdding Inheritance LinesGeneralization Lines (solid lines with closed arrowheads) indicate that asubclass extends superclass or an sub-interface extends asuper-interface. The arrow will point from the subclass (sub-interface) to thesuperclass (super-interface).1.In the Palette, highlight the "Generalization" option.2.Left-click on the desired subclass (sub-interface). A line will now beattached from that class/interface to the mouse pointer.3.Move the mouse to the desired superclass (super-interface) and left-click. Ageneralization line will be created and the associated Java code will beauto-generated. Green UML will not let you create a line that would resultin invalid Java code.Realization Lines (dotted lines with closed arrowheads) indicate that aclass implements an interface. The arrow will point from the class to theinterface.1.In the Palette, highlight the "Realization" option.2.Left-click on the desired class. A line will now be attached from thatclass/interface to the mouse pointer.3.Move the mouse to the desired interface and left-click. A realization linewill be created and the associated Java code will be auto-generated. GreenUML will not let you create a line that would result in invalid Java code.Adding Association and Composition LinesAssociation line s (tailless solid lines with open arrowheads) indicate that oneclass holds a static reference to another class or instance of an interface, i.e. it hasa field of the referenced type. The association line points from the class with thereference to the referenced class. Green UML has the erroneous notionunfortunately, that all such fields are initialized via constructor input parameters,so it auto-generates both the field and adds constructor code to initialize it via aconstructor input parameter. Unfortunately, this constructor code will need to bedeleted if one initializes the field in a different manner, such as by using a factoryobject.1.In the Palette, highlight the "Association" option.2.Left-click on the class you want to have the reference to the other class. Aline will now be attached from that class to the mouse pointer.3.Move the mouse to the desired interface and left-click. An association linewill be created and the associated Java code (field & constructor) will beauto-generated. Green UML will not let you create a line that would resultin invalid Java code.Composition lines (solid lines with no arrowheads and a diamond-shaped tail)indicate that one class holds a static reference to another class or instance of aninterface, i.e. it has a field of the referenced type, but also explicitly constructs theobjects being referenced. Colloquially, we say that one object "owns"another. The composition line points from the "owner" to the referencedclass. Green UML has the erroneous notion unfortunately, that all such fieldsare initialized via constructor input parameters, so it auto-generates both the fieldand adds constructor code to initialize it with the referenced class'sconstructor.. Unfortunately, this constructor code will need to be deleted if oneinitializes the field in a different manner, such as by using a factoryobject. Green UML is currently unable to handle an composition with an abstractclass or interface, which is rather common.1.In the Palette, highlight the "Composition" option.2.Left-click on the class you want to have the reference to the other class. Aline will now be attached from that class to the mouse pointer.3.Move the mouse to the desired interface and left-click. An association linewill be created and the associated Java code (field & constructor) will beauto-generated. Green UML will not let you create a line that would resultin invalid Java code.Adding Dependency Lines (not shown on screen shot above)Dependency lines (tailless dotted lines with open arrowheads) are used to indicate avariety of usually dynamic relationships between classes and interfaces, such as takinganother class as an input or returning it from a method, or instantiating it for use as alocal variable or value. If class "A" uses class "B", the dependency arrow will pointfrom class "A" to class "B".Green UML supports the two dependency scenarios. In the Palette, you may seeeither the "Instantiaton Dependency" or "Local AssignmentDependency" option. Clicking the small triangle next to the visible choice willshow you the other choice. A "push-pin" icon lets you show both options at once.Instantiation Dependency is when a method in one class instantiates another class foruse as a value in a method.1.Highlight the "Instantiaton Dependency" option and drawing a line fromthe class doing the instantiation to the one being instantiated. Green UML willwant you to only use concrete, classes that can be instantiated.2.A dialog box will appear asking you what method to put the code stub. The"cardinality" is simply how many instances you wish created.3.Green UML will generate the constructor call in the desired method.Local Assignment Dependency is when a method in one class creates a local variable of the type of the target class of the dependency.1.Highlight the "Local Assignment Dependency" option and drawing a linefrom the class doing the instantiation to the one being instantiated. The targetmay be an abstract class or an interface, but if it is, Green UML will ask youwhich concrete sub-class/implementation to actually instantiate.2.A dialog box will appear asking you what method to put the code stub. The"cardinality" is simply how many instances you wish created.3.Green UML will generate the constructor call and local variable assignment in thedesired method. The variable type will be the target of the dependency but theconstructor call will be to the selected concrete sub-type if the target isabstract. Green UML is not capable of auto-generating code for instantiating aconcrete subclass of a concrete superclass local variable.Adding Notes (not shown on screen shot above)Notes are just boxes of text placed on the diagram to help the reader understand itbetter.1.Highlight the "Note" option in the Palette.2.Left-click wherever you want the note to appear in the diagram.3.Fill out the text of the note box.Tips and TrapsExporation IconsGreen UML has a feature where it can automatically add the superclass or implementedinterface of a selected class onto the diagram. This is referred to as "incrementalexploring". If your diagram looks like the following, where an "ALL......" isdisplayed under the class name, the exploration feature is activated.Clicking on the "ALL" will display the superclass or interface. You can choose whatto show by right-clicking the class and selecting "Incrementally Explore".Clicking the "Toggle Exploration Icons" option in the Paletter will turn theincremental exploration feature on and off.Technical ErrorsGreen UML incorrectly uses an empty diamond symbol to denote a composition--theUML standard is to use a filled diamond. Empty diamonds are generally used for"aggregations" which closely resembles Green UML's "associations", which is really thegeneric term encompassing both aggregations and compositions. See, forinstance, /content/m11658/latest/ and /wiki/Class_diagram.BUG in Green 3.5.0 when branching in SVN: In this version (and presumably,earlier versions as well) of Green UML, the .GRN diagram file holds hard-codedreferences to the Eclipse project folder. These references are NOT updated when thesource code is branched and subsequently copied to another project folder. Thus, inthe branched code, the diagrams will appear blank because Green UML cannot find thesource files because it is looking in the wrong place. Work around:The .GRNdiagram files are just ASCII text files in an XML-like format. Use any text editor, e.g.Notepad, to open the file and globally search and replace all occurances of the oldproject folder name with the new project folder name.AmaterasUML官网：http://amateras.sourceforge.jp/cgi-bin/fswiki_en/wiki.cgi?page=AmaterasUML安装方法：解压后，把.jar文件(3个)拷贝到Eclipse的plugins目录下。
