Example 1 with ObjectMetadata

use of com.obs.services.model.ObjectMetadata in project alluxio by Alluxio.

the class OBSOutputStream method close.

 * Closes this output stream. When an output stream is closed, the local temporary file is
 * uploaded to OSS Service. Once the file is uploaded, the temporary file is deleted.
