Examples of org.akubraproject.BlobStoreConnection.sync()

org.akubraproject.BlobStoreConnection.sync()

Flush all blobs associated with this connection and fsync. After this method completes all data should be comitted to stable storage (for stores that are backed by stable storage). However, whether this is really the case will depend on the storage used by the store (e.g. for a local filesystem based store it'll depend on the OS config and hardware, i.e. whether the disk's write cache is flushed or not).

This may or may not flush any open output-streams. For reliable results ensure that all output streams are closed before calling sync. @throws IOException if any error occurred trying to flush and sync @throws UnsupportedOperationException if the store is not capable of syncing
