RTC v4.0.1+ Java API: how to load a workspace using Java API

Hi
I find my self struggling with a simple task:
given an RTC repository and a ready made workspace I want to download its content.

getting the repository instance was easy (there are online samples to do login):
  ITeamRepository repository = TeamPlatform.getTeamRepositoryService().getTeamRepository(rtcServerURL);
  ... then code  here perform a login...

then get an IWorkspaceConnection  using
IWorkspaceManager wm = SCMPlatform.getWorkspaceManager(repository)
IWorkspaceSearchCriteria criteria = IWorkspaceSearchCriteria.FACTORY.newInstance();
criteria.setExactName(rtcWorkspace);
criteria.setKind(IWorkspaceSearchCriteria.WORKSPACES);
... and then run a findWorkspace...

or maybe simply run :
ISharingManager sharingManager = FileSystemCore.getSharingManager();
        File workspaceRoot = ResourcesPlugin.getWorkspace().getRoot().getLocation().toFile();
        PathLocation pathlocation = new PathLocation(workspaceRoot.getAbsolutePath());
        ILocation sandBoxLocation = pathlocation.getCanonicalForm();
        ISandbox sandbox = sharingManager.getSandbox(sandBoxLocation, false);
        IRelativeLocation  relativeLocation = new RelativeLocation(new String[0]);
        Collection<ILoadRule> paramCollection = null;
ILoadOperation loadOp = IOperationFactory.instance.getLoadOperation(p);
loadOp.requestLoad(ISandbox paramISandbox, IRelativeLocation paramIRelativeLocation, Collection<ILoadRule> paramCollection, IProgressMonitor paramIProgressMonitor)

however, I'm not sure what to put in the params for the simplest load command.

can anyone help here ?

The filesystem operations aren't supported API yet. We are formalizing them, but we don't have an expected date for their release. In the meantime you are encouraged to use the commandline client. 


Supported API calls are those with javadoc in the 'doc' directory of the SDK.

You seem to have figured out the sandbox for the operation.

The relative location is where you want the content loaded in your sandbox. You can give it null if you want to load in the sandbox root.

ILoadRuleFactory will provide you with a way to create your load rule object from the file to pass to the operation.

Indeed ILoadRuleFactory class has a static factory to read files.
         ILoadRuleFactory.loadRuleFactory.getLoadRule(connection, input, progress)

but it requires a IWorkspaceConnection. How do I get from an ITeamRepository an IWorkspaceConnection ?

I mean I saw I can:
 IWorkspaceManager wm = SCMPlatform.getWorkspaceManager(repo);
 IWorkspaceConnection workspace = wm.createWorkspace(repo.loggedInContributor(), "Moti-Dependencies", "branch for the POC proof2", monitor);
but I'm afraid this code will create a new workspace . I want to load an existing workspace.

(assuming I want to load an existing workspace which was predefined in Concert Team client)

You already wrote the code to get those. Is there something else that you're missing?


mordechi taitelman commented Jul 04 '13, 11:07 a.m.

the search result is :
 java.util.List<IWorkspaceHandle> workspaceList =  wm.findWorkspaces(criteria, maxSize, monitor);

how can I get the IWorkspaceConnection from an IWorkspaceHandle ?
is IWorkspaceManager.createWorkspace really creates a new entity in the repository - or is it only a memory representation of an existing workspace ?

IWorkspaceManager#getWorkspaceConnection(IWorkspaceHandle, IProgressMonitor) would get you your connection.

The other call would create a new repository workspace, which isn't what you want.

here is what I did to load an existing workspace (need to attach the XML load rule file too)

and the loadrule XML file content is:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!--Built from the sandbox "/home/mordechi/dev/auto-dev-install" and the workspace "moti-master6.0-Workspace"-->

As an IBMer i find it sad there are not enough samples available online.
The whole Java API area is missing many samples.  Indeed you can download the JavaDoc but there is nothing like a good old code to explain simple/common tasks.
It can save hours/days for beginners in the RTC area.
