workspace.findFilesForLocation ? [message #326363]

I need to find files by filename, eg given "foo.java" I want all files
in the workspace that have <path>/foo.java.

This looks hopeful:
public IFile[] findFilesForLocation(IPath location)

Returns the handles of all files that are mapped to the given path in
the local file system. Returns an empty array if there are none. The
path should be absolute; a relative path will be treated as absolute.
The path segments need not be valid names. The resulting files may not
currently exist.

But it does not work, and the phrase "relative path will be treated as
absolute" is not at all helpful. What does that mean? "Apples will be
treated as oranges": do I get orange juice or apple juice?

If this function does not lookup files like I want, can anyone suggest a
function that might to it? Otherwise I have to sweep the workstation for
file names and create/maintain a table I guess.

Thanks,
John.

John,

It means that a path a/b will be treated as /a/b (or as c:/a/b on
windows). You could use an IResourceVisitor if you want to visit all
resource that match a particular path pattern. Of course a visitor and
this method only search the workspace itself, not your whole file system.

Thanks Ed for saving me some time. I implemented the visitor to build a
lookup table and hope my IResourceChangeListener will keep it up to date.
