使用eclipseuml2決議.uml檔案

2022-04-07 19:44:58 前端設計

我正在處理一項任務，我需要將 UML 圖轉換為我選擇的任何語言的原型。我通過 eclypse papyrus 創建了一個圖表并將其保存為 .uml 檔案。它包含用例、狀態機圖和類圖。將這些結合起來就足以創建一個原型——狀態代表螢屏及其后續。類圖提供了每個螢屏包含的資訊，用例圖提供了如何使用它的資訊。然后我希望將 uml 檔案加載到 java 代碼中。經過短暫的研究，eclipse uml2 包似乎是我所需要的——一個用于操作 UML 元素的工具。因此，我設法加載了 UML 檔案并以某種方式逐部分列印它：

import org.eclipse.emf.common.util.TreeIterator;
import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.EObject;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.emf.ecore.util.EcoreUtil;
import org.eclipse.uml2.uml.NamedElement;
import org.eclipse.uml2.uml.UMLPackage;
import org.eclipse.uml2.uml.resource.UMLResource;

import java.util.Collection;
import java.util.Iterator;

public class Loader {

    public Loader(){
        //default behaviour
        ResourceSet set = new ResourceSetImpl();
        set.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
        set.getResourceFactoryRegistry().getExtensionToFactoryMap()
                .put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
        Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap()
                .put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);

        Resource res = set.getResource(URI.createFileURI("C:/Users/gopco/workspace-papyrus/Test/Test.uml"), true);
        Resource model = set.createResource(URI.createFileURI("C:/Users/gopco/workspace-papyrus/Test/Test.uml"));

        for (TreeIterator<EObject> stuffInModel = res.getAllContents();
             stuffInModel.hasNext();) {
            EObject eObject = stuffInModel.next();
            System.out.println("--------------------------------------------");
            System.out.println(eObject.eContents());

        }
    }
}

但是，這會產生以下輸出（部分輸出）：

I cannot find clear description for this, how can I manipulate these objects? I need to determine which one is of what type (Eg. class, graph edge, actor, etc.) and according to that, create a UI representation - for example for a single state create a single screen. All I can find is commercial software converting UML to code, no opensource projects I could take inspiration from. Can somebody provide an example how to parse UML elements from .uml file and possibly process it (for examples, println is totally OK). Maybe it is described somewhere but I haven't found?

uj5u.com熱心網友回復：

研究檔案，在論壇上到處查看，我能夠為 UML 檔案撰寫一些基本的決議器。現在它只決議狀態機圖的一個元素，有未完成的可能屬性名稱串列，只是列印出名稱和值，但如果有人在尋找這樣的代碼，我會在這里添加它很難找到一些例子。我決議它的方式可能不是 100% 正確，但它似乎正在作業。
