To illustrate the ModelFilter plugin and its features, we will use a sample inspired from the Pet Store Application.
The models are available from the MoDisco SVN in subdirectory "examples/trunk/org.eclipse.gmt.modisco.usecase.modelfilter.sample" or from a downloadable archive. If you use a SVN client in Eclipse (Subversive or Subclipse), the project will be immediately available in your Eclipse workspace.
Sources of the Pet Store application are available here: http://www.oracle.com/technetwork/java/petstore1-3-1-02-139690.html
You may have to download several libraries to obtain an eclipse project without errors (JPA, JTA, JSF-apis and Servlets-jsp-apis). A complete bundle is also available from Mia-Software... To view this application in your Eclipse workspace, you will have to extract the content of this archive, and use the "import" wizard (import project in workspace).
To get the dependencies graph of a particular class, you have to right-click on the class in the Package Explorer, and select Discovery > Actions > Display Dependencies
Then, a graph displaying the dependencies will open:
Right-click on a project and select Discovery > Actions > Display Method Calls. A graph displaying all the method calls will open:
You will have a better look if we focus on a particular method. For example, the method public List<SelectItem> getCategories()
in class MapBean located in package com.sun.javaee.blueprints.petstore.mapviewer.
public List<SelectItem> getCategories() { // return categories for a JSF radio button ArrayList<SelectItem> arCats=new ArrayList<SelectItem>(); // get the CatalogFacade for the app FacesContext context=FacesContext.getCurrentInstance(); Map<String,Object> contextMap=context.getExternalContext().getApplicationMap(); CatalogFacade cf=(CatalogFacade)contextMap.get("CatalogFacade"); // get the categories from the database List<Category> catsx=cf.getCategories(); for(Category catx : catsx) { // add categories to be displayed in a radio button arCats.add(new SelectItem(catx.getCategoryID(), catx.getName())); } return arCats; }
Right-click on the method in the Package Explorer, and select Discovery > Actions > Display Method Calls:
To get the UML model with real type of properties, right-click on the java project you would like to inspect, and select Discovery > Discoverers > Create UML model with real types information on associations:
Then, you will have a complete UML model with the real types of Associations:
You will have a better look if we focus on a particular association. For example, the properties
private Collection<Item> items
in class Tag and
private Collection<Tag> tags
in class Item both located in package com.sun.javaee.blueprints.petstore.model.
