      public NfsFileOutputStream(NfsFile<?,?> nfsFile) throws IOException
      Creates a file output stream to write to the file represented by the specified NfsFile object, starting at offset = 0 and using syncType = FILE_SYNC (commit all data and metadata to stable storage before returning).

      If the file does not exist, it will first be created.

      Parameters:
      nfsFile - The file to be opened for writing.
      Throws:
      IOException - If the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason

      public NfsFileOutputStream(NfsFile<?,?> nfsFile, int syncType) throws IOException
      Creates a file output stream to write to the file represented by the specified NfsFile object, starting at offset = 0 and using syncType behavior.

      If the file does not exist, it will first be created.

      Parameters:
      nfsFile - The file to be opened for writing.
      syncType - One of the values below.
      • UNSTABLE = 0 - Best effort, no promises.
      • DATA_SYNC = 1 - Commit all data to stable storage, plus enough metadata for retrieval, before returning.
      • FILE_SYNC = 2 - Commit all data and metadata to stable storage before returning.
      Throws:
      IOException - If the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason
