queryCompletedResumableUpload(String uploadId, long totalBytes)

public abstract StorageObject queryCompletedResumableUpload(String uploadId, long totalBytes)

Attempts to retrieve the StorageObject from a completed resumable upload. When a resumable upload completes, the response will be the up-to-date StorageObject metadata.
