从日食中的ecore文件中读取eobjects [英] reading the eobjects from the ecore file in eclipse

问题描述

我有一个ecore文件，其中包含类eobjects.Now我想读取该ecore文件，并从该ecore文件中获取所有类eobjects。

解决方案

您是否意味着要使用自定义后缀重新装载特定的xmi文件？

以下是一个加载ecore的方法的示例文件在特定位置（路径）并返回您的根EObject

  public static EObject loadYourModel（String path）{
 / * Initialzie Models * / 
 YourPackage.eINSTANCE.eClass（）; 
 
 / *注册你的xmi资源* / 
 final Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE; 
 final Map< String，Object> m = reg.getExtensionToFactoryMap（）; 
 / *将所有不同的eco​​re文件后缀放在地图中; suffix = YourPackage.eNAME * / 
 m.put（YourPackage.eNAME，new XMIResourceFactoryImpl（））; 
 / *您可以将所有不同的包名称放在这里* / 
 
 / *创建一个新的资源集，以从文件中存储EObjects * / 
 ResourceSet resSet = new ResourceSetImpl ）; 
 
 / *获取您的ecore文件的资源* / 
资源资源= resSet.getResource（URI.createURI（path），true）; 
 / *获取您的模型的第一个元素= root hierachy * / 
 EObject root = resource.getContents（）。get（0）; 
返回根; 
} 
  

I have the ecore file which contains the class eobjects.Now i want to read that ecore file and get all the class eobjects from that ecore file.

解决方案

Do you mean you want to reload your specific xmi file with a custom suffix?

Here is an example of a method that loads an ecore file at a specific location (path) and returns your root EObject

public static EObject loadYourModel(String path) {
    /*Initialzie Models*/
    YourPackage.eINSTANCE.eClass();

    /*register your xmi resources*/
    final Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
    final Map<String, Object> m = reg.getExtensionToFactoryMap();
    /*put all your different ecore file suffixes in the map; suffix = YourPackage.eNAME*/
    m.put(YourPackage.eNAME, new XMIResourceFactoryImpl());
    /*you can put all different package names here*/

    /*Create a new Resource set to store the EObjects from the file*/
    ResourceSet resSet = new ResourceSetImpl();

    /*get the resource of your ecore file*/
    Resource resource = resSet.getResource(URI.createURI(path), true);
    /*Get the first element = root of your model hierachy*/
    EObject root = resource.getContents().get(0);
    return root;
}
