Note: this internal interface is slightly different from public APIs in regard to handling of the qualifier. Here we differ from the public Java API in that null != byte[0]. Rather, we respect qual == null as a request for the entire column family. The caller ( get(ByteBuffer, ByteBuffer, ByteBuffer, Map)) interface IS consistent in that the column is parse like normal.
