仅在 Intelij-Idea 中查找指定类的方法用法

Question

I am using Intelijidea and I have problem with method usage finding.

Suppose I have interface Worker.

public interface Worker {

    void startWork();
    void endWork();
}

And I have two implementation.

public class Develper implements Worker {
    @Override
    public void startWork() {
        System.out.println("Developer Start Working");
    }

    @Override
    public void endWork() {

    }
}

public class Qa implements Worker {
    @Override
    public void startWork() {
        System.out.println("QA start Work");
    }

    @Override
    public void endWork() {

    }
}

I open Developer class and trying to find usage of startWork. I want only to view usage of Developer.startWork implemented method.

but when i find usage it shows both Developer and Qa startWork method usages. how can i avoid Qa.startWork method usage when finding Developer.startWork usages.

Please advice.

Answer 1

Using Ctrl + Shift + Alt + F7 ( ⌘ + ⇧ + ⌥ + F7 for Mac) should show the prompt from Jim Hawkins answer.

See: https://www.jetbrains.com/help/idea/find-usages-method-options.html

When you search for usages of a method implementation with this dialog Ctrl+Shift+Alt+F7, IntelliJ IDEA will ask whether or not you want to search for the base method. With any other find usages actions such as Alt+F7 or Ctrl+Alt+F7, the base method will be included in the search results automatically.

Answer 2

I'm using IntelliJ IDEA 15.0.1 .

I think what you see when using the "find usages" functionality depends from the context.

If you place the cursor in method name Developer.startWork and invoke find usages , you should see a small dialog. You are asked "Do you want to find usages of the base method?" .

If you say "No", and in your sources you did only call the method via the base class or interface ( Worker.start() in your example), IDEA doesn't show you any hits. Thats correct.

If you call the overridden method via Developer.startWork() , and press "No" in the dialog, then you will see the usages of the specific implementation.

Update:

Answer 3

After reading the answer from @JimHawkins, I think the elephant is still in the room :) The question is, do you want to see where Developer#startWork is actually called, or do you want to see where it is statically referenced?

Eg:

Developer developer = new Developer();
developer.startWork(); // you want to find only this?
Worker worker = developer;
worker.startWork(); // ..or this as well?

The find usages method can only tell, where a given method is statically referenced, but not where it is actually used (that is determined runtime via the mechanism of polymorphism ).
