How to find forward reference in eclipse?
Is there any way by which I can find out all classes which implement a pa开发者_如何转开发rticular interface? For example, if I have a interface as follows:
public interface myIntFac{}
I want to find all classes inside current project that implement this interface. How can I find it out in Eclipse?
At the interface level, you can use (assuming the cursor in on the interface)
- CTRL+T to show the Quick Type Hierarchy
- F4 to Open Type Hierarchy
At the method level, if you hover a method while holding down the control key, a pop-up box gives you the following choices:
- Open Declaration
- Open Implementation
(source: eclipse.org)
And from anywhere, you can use:
- CTRL+SHIFT+H to open the Open Type Hierarchy pop-up and search for any type/interface.
Place your cursor on the interface, and try Ctrl-T.
Put your cursor in myIntFac
and press F4 to show the type hierarchy as a separate window, or Ctrl-T to show it as a pop-up. Personally I like the "separate window" approach as it makes it easier to browse, refocus on a different type etc - but if you only want to show the hierarchy very briefly, the pop-up is good too.
