From ea3ff9eaaa508b9cbc7f52bc92d189eacbc7a935 Mon Sep 17 00:00:00 2001 From: tonikitoo Date: Tue, 2 Aug 2016 11:52:28 -0700 Subject: Introduce ::getPropertyInternal method to avoid duplication Document.cpp implements "getter" methods for some of the Document object properties. Some of the body of such methods are identical. Patch introduces a ::getPropertyInternal private method that gets rid of this duplication. Namely the following properties' getters are cleaned up: - "author", "creationDate", "creator", "keywords", - "modDate", "producer", "subject" and "title" No behavior change.
