带有 eclipse uml2 的 Parse.uml 文件

[英]Parse .uml file with eclipse uml2

问题描述

我正在执行一项任务，我需要将 UML 图转换为我选择的任何语言的原型。 我通过 eclypse papyrus 创建了一个图表并将其保存为 .uml 文件。 它包含用例，state机器图和class图。 将这些结合起来应该足以创建一个原型——状态代表屏幕及其后续操作。 Class 图提供了每个屏幕包含的信息，用例图提供了如何使用它的信息。 然后我希望将 uml 文件加载到 java 代码。 经过短暂的研究，eclipse uml2 package 似乎是我需要的 - 一个用于操作 UML 元素的工具。 因此，我设法加载了 UML 文件并以某种方式逐部分打印它：

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，这会产生以下 output（其中的一部分）：

我找不到对此的明确描述，我该如何操作这些对象？ 我需要确定哪个是什么类型（例如 class、图边、演员等），并根据此创建一个 UI 表示 - 例如，对于单个 state 创建一个屏幕。 我所能找到的只是将 UML 转换为代码的商业软件，没有我可以从中获得灵感的开源项目。 有人可以提供一个示例，说明如何从 .uml 文件解析 UML 元素并可能对其进行处理（例如，println 完全可以）。 也许它在某处被描述但我没有找到？

研究文档，在论坛上四处寻找，我能够为 UML 文件编写一些基本的解析器。 现在它只解析 state 机器图的一个元素，有未完成的可能 attr 名称列表，只打印出名称和值，但如果有人正在寻找这样的代码，我会在这里添加它，因为它很难找到一些例子。 我解析它的方式可能不是 100% 正确，但它似乎有效。
