Re: check out a single file?

Hello,

While sparse checkout feature is not yet available I'd suggest you to
use SVNRepository API to implement editing file.

To get file contents you may obviously use SVNRepository.getFile(...)
method. To commit modified version later, you may use the following snippet:

String parentDirURL = "file:///c:/users/alex/sandbox/repos/dir";
String fileName = "file.txt";
byte[] newContents = new byte[] {'a', 'b', 'c'};
InputStream is = new ByteArrayInputStream(newContents);

SVNDeltaGenerator generator = new SVNDeltaGenerator();
SVNURL url = SVNURL.parseURIEncoded(parentDirURL);
SVNRepository repos = SVNRepositoryFactory.create(url);

ISVNEditor commitEditor = repos.getCommitEditor("message", null);
try {
commitEditor.openRoot(-1);
commitEditor.openFile(fileName, -1);
commitEditor.applyTextDelta(fileName, null);
String checksum =
generator.sendDelta(fileName, is, commitEditor, true);
commitEditor.closeFile(fileName, checksum);
commitEditor.closeDir();
SVNCommitInfo info = commitEditor.closeEdit();
System.out.println(info);
commitEditor = null;
} finally {
if (commitEditor != null) {
commitEditor.abortEdit();
}
repos.closeSession();
}
