From 5428555d7bca8116fa8c6d6914674f2c2adb17ac Mon Sep 17 00:00:00 2001 From: Lei Zhang Date: Fri, 9 Oct 2015 13:57:36 -0700 Subject: Merge to XFA: Sanitize CJBig2_SymbolDict's memory usage. - Use std::vector instead of storing pointers to arrays. - Make CJBig2_SymbolDict's members private with accessors. - Use std::vector in related places. - Steal Chromium's vector_as_array() and use it as an adaptor as needed.
