Jump into interface implementation in Eclipse IDE

 

You know how in Eclipse, pressing F3 over a method will take you to its declaration? Well I have a method that is part of an interface; clicking F3 over this naturally takes me to the declaring interface.

Obviously there is an object implementing this interface and this is where the method is actually implemented. I want, when I press F3, to jump to the implementation, not the interface declaration. I know that the implementation may not be known at compile-time, so is there a way for Eclipse to show me all the classes implementing the interface so that I can select which implemented method to view? Right now when this happens I am just manually searching for this to find the implemented method.

Here's what I do:

  • In the interface, move the cursor to the method name. Press F4. => Type Hierarchy view appears
  • In the lower part of the view, the method should already be selected. In its toolbar, click "Lock view and show members in hierarchy" (should be the leftmost toolbar icon).
  • In the upper part of the view, you can browse through all implementations of the method.

    • The procedure isn't very quick, but it gives you a good overview.

    Well... well... I hope you use Eclipse Helios, because what you asked is available on Helios.

    Put your text cursor again on the method and click menu Navigate → Open Implementation. Now if you have more than one implementation of the method, you will get choice to pick which implementation to open.

    By defining a keybinding on Preferences → General → Keys you can even use the feature easier, but before you do that, see if this shortcut is fast enough for you.

    Press Ctrl + click and hold. Now move your mouse over the same method. Tadam… you will get choice.

    If you pick Open Implementation you'll get the same choice as before.

    Press Ctrl + T on the method name (rather than F3). This gives the type hierarchy as a pop-up so is slightly faster than using F4 and the type hierarchy view.

    Also, when done on a method, subtypes that don't implement/override the method will be greyed out, and when you double click on a class in the list it will take you straight to the method in that class.
