Can one use CSSDK to determine if user can unlock file locked by another?

Environment[indent]TS 7.2.1 Patch 1 on Linux[/indent]
Task At Hand[indent]I am trying to figure out if it is possible, through CSSDK, to determine if a given user has the ability to unlock a file locked by another - without (or in advance of) actually trying to perform the unlock operation.

I was figuring that I'd start with something like:

...
CSUser user = someMethod(); /* this part is not important, I can get the user object */
CSRole[] roles = user.getRoles(/* what goes here? */);
for (CSRole role : roles) {
    CSOperation[] ops = role.getOperations();
    for (CSOperation op : ops) {
        if (op.getName().matches("UnlockFile")){
            /* ... */
        }
    }
}
...

try experimenting with this: csFile.getRoles(csClient.getCurrentUser()).getOperations();

From what it looks like: it might get you just the operations specific to a csUser on a specific file rather than parsing thru all permissions the user has in teamsite.

I decided to take a different approach - instead of looking at the operations, I'm going to stop at the role level, and just check to see if the user has a role of editor or admin or master - all of which whom can unlock files locked by someone else - if they do I can set a Boolean flag to true, otherwise I'll set it to false.

It should do what I want ... I hope ...

I think the original code would have been okay except that I think the "UnlockFiles" operation is evaluated contextually rather than having distinct options like "UnlockMyFiles" and "UnlockOthersFiles"

FWIW - this is for code in a JSP/Java CGI that allows users to either detach or unlock locked files that get attached to the job after the AttachDependencies task (PLC) - and I'm trying to deal gracefully with the fact that Authors cannot unlock files locked by someone else and so must detach them (as per local design / requirements).

Right now the code just throws an exception - which isn't a very good UI...

That's probably best in the long run, but CSNode#isPermitted(CSOperation) in combination with CSClient#getOperation("UnlockFile") is what you want (where your instance of CSNode is a CSSimpleFile that you obtained in any number of ways).

[EDIT] PS: the missing part of the java code in your original post is that having a role granting 'UnlockFile' is not sufficient to unlock *someone else's* files. For that, you also need CSRole#isOverrideWorkareaPermissions(). This would be the approach if you want to check at a branch level, rather than on a specific file. In this case, you get the array of CSRoles via csclient.getCurrentUser().getRoles(CSBranch).
