From e533b93601c7e9eb328619681a78c188d1a89191 Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Thu, 16 Mar 2017 11:47:20 -0400 Subject: Create common base class for TxtBreak and RTFBreak. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This CL starts extracting common members between the two break classes into a common base class. This also normalizes some of the member names to be the same across classes.
