在 Eclipse for Java 中的单独一行上包装链式方法调用

Wrapping chained method calls on a separate line in Eclipse for Java

提问by Johann

I haven't been successful in figuring out how to wrap each method call in Eclipse. For example, I have this:

我还没有成功弄清楚如何将每个方法调用包装在Eclipse. 例如，我有这个：

someObject.A().B().C();

But I really want this:

但我真的想要这个：

someObject.A()
          .B()
          .C();

Nothing under the "Line Wrapping" section in Eclipseseems to give me this result.

“换行”部分下的任何内容Eclipse似乎都没有给我这个结果。

Complementing Deepak Azad's answer, what you exactly need is the following:

补充 Deepak Azad 的回答，您真正需要的是以下内容：

Windows: Window → Preferences → Java → Code Style
→ Formatter → Edit → Line wrapping (tab)

Mac OS: ADT → Preferences → Java → Code Style
→ Formatter → Edit → Line wrapping (tab)

Windows：窗口 → 首选项 → Java → 代码样式
→ 格式化程序 → 编辑 → 换行（选项卡）

Mac OS：ADT → 首选项 → Java → 代码样式
→ 格式化程序 → 编辑 → 换行（选项卡）

Then, in the list at the left, select:

然后，在左侧的列表中，选择：

Function Calls → Qualified invocations

函数调用 → 限定调用

Now below this list, set Line wrapping policyto:

现在在此列表下方，将换行策略设置为：

Wrap all elements, except first element if not necessary

包装所有元素，如果不需要，除了第一个元素

Check:

检查：

Force split, even if line shorter than maximum line width

强制拆分，即使线短于最大线宽

Finally, set Indentation policyto (thanks @Turbo):

最后，将缩进策略设置为（感谢@Turbo）：

Indent on column

列缩进

It should give you the exact behavior you asked for.

它应该为您提供您要求的确切行为。

Window → Preferences → Java → Code Style → Formater → Edit → Line wrapping → Never join already wrapped lines

窗口 → 首选项 → Java → 代码样式 → 格式化程序 → 编辑 → 换行 → 永远不要加入已经换行的行

Window > Preferences > Java > Code Style > Formater > Edit > Line wrapping > Function Calls, set the 'Line wrapping policy' as 'Wrap all elements, every element on a new line'.

Window > Preferences > Java > Code Style > Formater > Edit > Line wrapping > Function Calls，将'Line wrapping policy'设置为'Wrap all element, every element on a new line'。

For those who have eclipse code formatting settings checked into source control (for consistent code formatting across the whole team), the .settingsfolder is checked in.

对于那些将 Eclipse 代码格式设置签入源代码管理（为了在整个团队中保持代码格式一致）的人，将.settings签入该文件夹。

The property that will give you this formatting behavior is in the .settings/org.eclipse.jdt.core.prefsfile.

为您提供这种格式化行为的属性在.settings/org.eclipse.jdt.core.prefs文件中。

The property is:

该物业是：

org.eclipse.jdt.core.formatter.alignment_for_selector_in_method_invocation=80

If you are willing to do the formatting of those segments yourself, you can prevent eclipse from reformatting those segments by using:

如果您愿意自己格式化这些段，则可以使用以下方法防止 Eclipse 重新格式化这些段：

// @formatter:off
...
// @formatter:on

You might need to enable this in your preferences: http://archive.eclipse.org/eclipse/downloads/drops/R-3.6-201006080911/eclipse-news-part2.html#JavaFormatter

您可能需要在您的首选项中启用它：http: //archive.eclipse.org/eclipse/downloads/drops/R-3.6-201006080911/eclipse-news-part2.html#JavaFormatter
