  @Deprecated
  public interface RecordWriteChannel
  extends java.nio.channels.WritableByteChannel

  A WritableByteChannel for writing records to a FileWriteChannel.

  The format of these records is defined by the leveldb log format: http://leveldb.googlecode.com/svn/trunk/doc/log_format.txt

  An instance of RecordWriteChannel may be obtained from the method: FileService.openRecordWriteChannel(AppEngineFile, boolean).

  Just like WritableByteChannel If one thread initiates a write operation upon a channel then any other thread that attempts to initiate another write operation will block until the first operation is complete.
