使用 EMF 从 XMI 读取序列图

Question

我搜索了很多有关使用 EMF 从 XMI 读取 UML 图的信息 Java 蚀。我只找到了阅读 class 图的解决方案，但我的任务是从 XMI 读取序列图。谁能帮帮我？

Answer 1

经过一番努力终于找到了一个可行的解决方案，你只需要将无错误的UML图路径放在主class，提供的代码将读取所有节点和子- 节点分别。您可以根据您的要求自定义代码。此代码可用于 class 图和序列图。

public static void main(String[] args) {
     MododelLoader umlModel= new ModelLoader();
    // sequence diagram XMI
     String umlFilePath = "SequenceDiagramUML\sequenceDiagram.uml"; 

        String uri = null;
        try {
            uri = umlModel.getFileURI(umlFilePath);
        } catch (Exception e) {
            e.printStackTrace();
        }
        Object objModel = umlModel.loadModel(uri);
        Model sourceModel;
        EList<PackageableElement> sourcePackagedElements = null;
        if (objModel instanceof Model) {
            sourceModel = (Model) objModel;
            sourcePackagedElements = sourceModel.getPackagedElements();
        } else if (objModel instanceof Package) {
            Package sourcePackage = (Package) objModel;
            sourcePackagedElements = sourcePackage.getPackagedElements();
