How to get tree structure from SVN using java

问题

Is there any way to get the SVN structure as a tree struture in java?

For Eg: if i specify a path http://sample.com/repository/pag/branches/dev/Structure/services/

I want what all entries under services and if it again contains a directory its enteries also in a tree?

Thanks.

Note : i have seen the getDir(). But here i have to keep on iterating it.

If you need all the tree, you may do that with "status" request with report telling that you have an empty working copy. One "status" request should be faster than a number of getDir() requests. An example how to do that with SVNKit

   final SVNRepository svnRepository = SVNRepositoryFactory.create(url);
    try {
        svnRepository.status(revision, "", SVNDepth.INFINITY, new ISVNReporterBaton() {
            @Override
            public void report(ISVNReporter reporter) throws SVNException {
                reporter.setPath("", null, revision, SVNDepth.INFINITY, true);
                reporter.finishReport();
            }
        }, new ISVNEditor() {
            @Override
            public void targetRevision(long revision) throws SVNException {

            }

            @Override
            public void openRoot(long revision) throws SVNException {
                System.out.println("<root>");
            }

            @Override
            public void deleteEntry(String path, long revision) throws SVNException {
            }

            @Override
            public void absentDir(String path) throws SVNException {
            }

            @Override
            public void absentFile(String path) throws SVNException {
            }

            @Override
            public void addDir(String path, String copyFromPath, long copyFromRevision) throws SVNException {
                System.out.println("directory: " + path);
            }

            @Override
            public void openDir(String path, long revision) throws SVNException {
            }

            @Override
            public void changeDirProperty(String name, SVNPropertyValue value) throws SVNException {
            }

            @Override
            public void closeDir() throws SVNException {
            }

            @Override
            public void addFile(String path, String copyFromPath, long copyFromRevision) throws SVNException {
                System.out.println("file: " + path);
            }

            @Override
            public void openFile(String path, long revision) throws SVNException {
            }

            @Override
            public void changeFileProperty(String path, String propertyName, SVNPropertyValue propertyValue) throws SVNException {
            }

            @Override
            public void closeFile(String path, String textChecksum) throws SVNException {
            }

            @Override
            public SVNCommitInfo closeEdit() throws SVNException {
                return null;
            }

            @Override
            public void abortEdit() throws SVNException {
            }

            @Override
            public void applyTextDelta(String path, String baseChecksum) throws SVNException {
            }

            @Override
            public OutputStream textDeltaChunk(String path, SVNDiffWindow diffWindow) throws SVNException {
                return null;
            }

            @Override
            public void textDeltaEnd(String path) throws SVNException {
            }
        });
    } finally {
        svnRepository.closeSession();
    }
