de.fu_berlin.inf.dpp.activities.business.ChecksumActivity
A checksum activityDataObject is used to communicate checksums from the host to the clients. A checksum activityDataObject always relates to a certain file (given a path) and contains the hash and length of the file. To indicate that a file is missing on the host NON_EXISTING_DOC is used. A checksum activityDataObject also may contain a JupiterTimestamp to indicate at which point of time the checksum was created. A buddy can use this information to see whether the checksum can be used to check for consistency or whether the local user has already written additional text which invalidates the checksum.

                    final DocumentChecksum checksum = new DocumentChecksum(path);
                    checksum.bind(doc);
                    checksum.update();
                    Utils.runSafeSWTSync(log, new Runnable() {
                        public void run() {
                            sarosSession.activityCreated(new ChecksumActivity(
                                user, path, checksum.getHash(), checksum
                                    .getLength()));
                        }
                    });
                } catch (CoreException e) {
