From c1ad3676c4b56b80663d271ac367a65cc41c39ab Mon Sep 17 00:00:00 2001 From: Binh-Minh Ribler Date: Sun, 26 Jul 2009 23:00:17 -0500 Subject: [svn-r17238] Purpose: Fix bug and improve readability Description: - Revised DataSet::write to pass in correct string buffer - Added member function DataSet::getInMemDataSize() to simplify getting the dataset's data size in memory. - Added private functions for reading fixed- and variable-length string data: p_read_fixed_len and p_read_variable_len. - Added tests to write/read array of strings to datasets.
