Eclipse 查找方法的引用

Question

I wanted to find all the callers of the the method "get" for the following class:

package com.zzz.zzz.zzz.services;

public final class EMF {
  private static final EntityManagerFactory emfInstance =
    Persistence.createEntityManagerFactory("obamaCareIsGood4U");

  private EMF() {}

  public static EntityManagerFactory get() {
    return emfInstance;
  }
}

So I highlited the text "get" and right-clicked References - project. But it returned references to every method called "get", rather than just references to com.zzz.zzz.zzz.services.EMF.get().

Is this an eclipse bug? How do I get Eclipse to show references only to com.zzz.zzz.zzz.services.EMF.get()?

Answer 1

With get highlighted, hit Ctrl+Shift+G. It'll come up with a list of results in the search tab/window. It'll find all references within your workspace. It does it via proper references, and not a plain text search.

Answer 2

Find references in Project relies on method name, that's why it's not accurate. Try using Call Hierarchy.

Answer 3

In Eclipse Kepler you can configure the search to filter out all Potential Matches (when using References - Workspace / Project or Hierarchy . To activate the filter, click the small down-arrow at the right top of the Search view and activate the Potential Matches check-box.

Answer 4

Sometimes, if you have multiple methods of the same name, eg, constructors of a class, all with the same name but different signature, for example, it can be a pain to find all callers of one of those constructors. A trick you can use is to comment out the one you are investigating, and build. The compiler will then tell you all the places it is unable to find that signature, and hence these are exactly all the places that are trying to call that method with that name and that particular signature.

Answer 5

Eclipse continues to have a bug, where Search->References->Workspace does not find method references.
