Eclipse - find all classes that extend interface
提问by Marcus Leon
We have an interface that has a child interface. Ie:
我们有一个接口，它有一个子接口。IE：
public interface GenCalculator extends Serializable {}
public interface SpecialCalculator extends GenCalculator {}
In Eclipse, how can you find all interface-s that extend in this case GenCalculator?
在 Eclipse 中，如何找到在这种情况下扩展的所有接口GenCalculator？
If I right click, select "Open Type Hierarchy" in the GenCalculatorinterface, I only see classes that implement that GenCalculatorinterface. I want to see everything - those that implement and those that extend.
如果我右键单击，在GenCalculator界面中选择“Open Type Hierarchy” ，我只会看到实现该GenCalculator界面的类。我想看到一切——那些实现的和那些扩展的。
We're on Eclipse v.3.2.2.
我们使用的是 Eclipse v.3.2.2。

Ctrl+T查看所有后代
Press it the combination a second time (see fine print in initial popup) if you want to display super interfaces/classes.
如果要显示超级接口/类，请再次按下它的组合（请参阅初始弹出窗口中的细则）。

Click on GenCalculatorin the editor and press CTRL+T. You will see the quick complete hierarchy.
GenCalculator在编辑器中单击并按CTRL+T。您将看到快速完整的层次结构。
It is possible to have that aswell in the "Open Type Hierarchy" view, but you will have to switch the different options (button in the upper right corner).
也可以在“Open Type Hierarchy”视图中使用它，但您必须切换不同的选项（右上角的按钮）。

You can't do it in only one search.
您不能仅通过一次搜索来完成。
May be you could use the "Text Search" option and wildcards, something like searching for "*s YourInterfaceName" (trying to catch "extendsYourInterfaceName" and "implementsYourInterfaceName") but is too tricky.
也许您可以使用“文本搜索”选项和通配符，例如搜索“*s YourInterfaceName”（试图捕获“extend sYourInterfaceName”和“implement sYourInterfaceName”），但太棘手了。

You can do it with nWire for Java. However, nWire requires Eclipse 3.3 and above. I highly recommend upgrading.
您可以使用nWire for Java 来实现。但是，nWire 需要 Eclipse 3.3 及更高版本。我强烈建议升级。

You CAN do this, but it doesn't involve the Type Hierarchy.
您可以这样做，但它不涉及类型层次结构。
In the Eclipse editor pane, highlight the name of the class of which you want to find extending classes.
在 Eclipse 编辑器窗格中，突出显示要查找其扩展类的类的名称。
Then go to Search > Java Search and the name of that class should be prepoplated in the search field.
然后转到“搜索”>“Java 搜索”，该类的名称应预填充在搜索字段中。
Check the 'Limit To > Implementors' radio button.
选中“限制到 > 实施者”单选按钮。
Click the Search button.
单击搜索按钮。
