Jump into interface implementation in Eclipse IDE

Question

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.

There's a big productivity boost if you add an Alt + F3 key binding to the Open Implementation feature, and just use F3 to go to interfaces, and Alt + F3 to go to implementations.

Highlight an interface and use Ctrl+T to open "Quick Type Hierarchy".
