使用 eclipse uml2 解析 .uml 文件
Parse .uml file with eclipse uml2
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、状态机图和 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 包似乎是我所需要的——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.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，这会产生以下输出（部分）：

我找不到对此的明确描述，我该如何操作这些对象？我需要确定哪一个是什么类型（例如 class、图边、演员等），并据此创建一个 UI 表示 - 例如，对于单个状态创建一个屏幕。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）。也许在某处有描述，但我没找到？
通过研究文档，在论坛上到处查看，我能够为 UML 文件编写一些基本的解析器。现在它只解析状态机图的一个元素，有未完成的可能 attr 名称列表，只是打印出名称和值，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。可能我解析它的方式不是 100% 正确，但它似乎有效。

我找不到对此的明确描述，我该如何操作这些对象？我需要确定哪一个是什么类型（例如 class、图边、演员等），并据此创建一个 UI 表示 - 例如，对于单个状态创建一个屏幕。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）。也许在某处有描述，但我没找到？
通过研究文档，在论坛上到处查看，我能够为 UML 文件编写一些基本的解析器。现在它只解析状态机图的一个元素，有未完成的可能 attr 名称列表，只是打印出名称和值，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。可能我解析它的方式不是 100% 正确，但它似乎有效。
