From bc75f1737f7eb8d45c5a2ebd3ad78203782c1642 Mon Sep 17 00:00:00 2001 From: Lei Zhang Date: Tue, 22 Dec 2015 13:46:40 -0800 Subject: Merge to XFA: Convert CPDF_Parser::m_CrossRef to a std::map. This improvements memory usage in case PDFs have sparse object numbers. The map holds a struct that currently has only one member. The struct will contain more members as other internal data structures get converted. BUG=pdfium:111 TBR=weili@chromium.org Review URL: https://codereview.chromium.org/1539573003 .
