如何在Eclipse插件中以编程方式设置TextEditor的String输入？ [英] How to programatically set String input of TextEditor in Eclipse plug-in?

问题描述

我想要的东西：我想为我的Eclipse编辑器插件编写JUnit测试。为此，我想设置我的 TextEditor 扩展的实例。然后，我想从字符串中设置此 TextEditor 的输入，以便该字符串的内容是编辑器实例的输入。然后，我想运行一些测试并断言编辑器标记了错误，依此类推。

What I want: I want to write JUnit tests for my Eclipse editor plug-in. For this I want to set up an instance of my TextEditor extension. Then I want to set the input of this TextEditor from a String, so that the content of the String is the input of the editor instance. Then I want to run some tests and assert that the editor marks errors and so on.

失败的地方：我不知道如何从字符串设置编辑器的输入。编辑器唯一要做的功能就是 setInput（IEditorInput input），但是我不知道如何创建ÌEditorInput带有字符串作为内容。

Where I fail: I don't know how to set up the input of the editor from a String. The only function the editor has to do so is setInput(IEditorInput input), but I don't know how to create an ÌEditorInput with a String as it's content.

是否有可能这样做，如果没有，可以通过其他任何方式将编辑器的输入设置为给定值

Is there any possibility to do so and, if not, any other way to set the input of the editor to a given String?

推荐答案

您可以创建一个（工作区）文件为 Greg 建议或实施专门的 IEditorInput 并使用此输入打开文本编辑器。

You can either create a (workspace) file as Greg suggested or implement a specialized IEditorInput and open a text editor with this input.

例如：

// uninteresting methods left out for brevity

class StringEditorInput implements IStorageEditorInput {
  @Override
  public boolean exists() {
    return true;
  }

  @Override
  public IStorage getStorage() throws CoreException {
    return new StringStorage();
  }
}

class StringStorage implements IStorage {
  @Override
  public InputStream getContents() throws CoreException {
    return new ByteArrayInputStream( "Hello editor!".getBytes( StandardCharsets.UTF_8 ) );
  }
}

String editorId = "org.eclipse.ui.DefaultTextEditor";
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IEditorPart editor = IDE.openEditor( page , new StringEditorInput(), editorId );
