From 55787cc0d0ecdbd060f7ee1caaaab90d2482eb67 Mon Sep 17 00:00:00 2001 From: Chander Sudanthi Date: Fri, 2 Nov 2012 11:32:00 -0500 Subject: base: split out the VncServer into a VncInput and Server classes This patch adds a VncInput base class which VncServer inherits from. Another class can implement the same interface and be used instead of the VncServer, for example a class that replays Vnc traffic. --HG-- rename : src/base/vnc/VncServer.py => src/base/vnc/Vnc.py rename : src/base/vnc/vncserver.cc => src/base/vnc/vncinput.cc rename : src/base/vnc/vncserver.hh => src/base/vnc/vncinput.hh --- src/base/vnc/vncinput.cc | 130 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 130 insertions(+) create mode 100644 src/base/vnc/vncinput.cc (limited to 'src/base/vnc/vncinput.cc') diff --git a/src/base/vnc/vncinput.cc b/src/base/vnc/vncinput.cc new file mode 100644 index 000000000..526f61bc1 --- /dev/null +++ b/src/base/vnc/vncinput.cc @@ -0,0 +1,130 @@ +/* + * Copyright (c) 2010 ARM Limited + * All rights reserved + * + * The license below extends only to copyright in the software and shall + * not be construed as granting a license to any other intellectual + * property including but not limited to intellectual property relating + * to a hardware implementation of the functionality of the software + * licensed hereunder.
