List of linkToSnapshot() Examples

Examples of linkToSnapshot()

org.xtreemfs.babudb.index.LSMTree.linkToSnapshot()
Links the LSM tree to a new snapshot file. The on-disk index is replaced with the index stored in the given snapshot file, and all in-memory snapshots are discarded. @param snapshotFile the snapshot file @throws IOException if an I/O error occurred while reading the snapshot file

Examples of org.xtreemfs.babudb.index.LSMTree.linkToSnapshot()

            // snapshot; this is done to ensure that old checkpoints are
            // properly cleaned up, and the database remains in a consistent
            // state
            IOException exception = null;
            try {
                tree.linkToSnapshot(databaseDir + File.separator
                    + getSnapshotFilename(index, viewId, sequenceNo));
            } catch (ClosedByInterruptException exc) {
                Logging.logError(Logging.LEVEL_DEBUG, this, exc);
            } catch (IOException exc) {
                Logging.logError(Logging.LEVEL_ERROR, this, exc);
