It sounds like you want something like References->Workspace (Control+Shift+G) rather than the call hierarchy?

Have you used this option before? It uses FindReferencesAction, take a look at this class and you can see it building up a search query based on the currently selected IJavaElement.

Could you use this as a basic for a search query on multiple IJavaElements? Or do you want your own specific view?

I am not intending to create a seperate view,but i would like to write it into a file. view is not important. I just want to get the references. as objets is also fine.For your first question yes i have used it too. I do not mind using wither of these searches – Ravisha Mar 22 '11 at 04:05
How are you going to drive it? Is it from selecting a some IJavaElement(s)? – katsharp Mar 22 '11 at 09:33
Looks like a there could be a hacky way of doing it via running the search from the FindReferencesAction, then accessing the search results from the search query – katsharp Mar 22 '11 at 09:34
I will be having a list of strings containing class names for which i need to find the references in a given project – Ravisha Mar 23 '11 at 03:47

Have a look at the OpenCallHierarchyAction class of the org.eclipse.jdt.ui.internal.callhierarchy Package. This is internal Eclipse source code, but the code in the run(ITextSelection selection) method should be interesting to you.

Kool this is what i was searchin for. although adding reference of this into plug in project needs to include "org.eclipse.jdt.ui.source" in dependency. – Ravisha Mar 24 '11 at 04:50

Before you write anything like this, make sure you take a look at JDepend4Eclipse, it may do much of what you need. I have used it in the past to do package-level refactoring as well as understanding (and removing) circular dependencies.

If it doesn't do what you need, you may want to peek at their source code.
