From 5f4bbe6e9e08f5f76eada84497a7530ffb08fbf1 Mon Sep 17 00:00:00 2001 From: Alexander Tkachev Date: Tue, 24 May 2016 16:19:22 +0600 Subject: CLOUD: Add OneDrive Storage stub Knows how to OAuth already. This commit also adds CloudManager::addStorage(), so OneDriveStorage can add newly created Storage and CloudManager can save it in the configuration file. --- backends/cloud/onedrive/onedrivestorage.cpp | 151 ++++++++++++++++++++++++++++ backends/cloud/onedrive/onedrivestorage.h | 119 ++++++++++++++++++++++ 2 files changed, 270 insertions(+) create mode 100644 backends/cloud/onedrive/onedrivestorage.cpp create mode 100644 backends/cloud/onedrive/onedrivestorage.h (limited to 'backends/cloud/onedrive') diff --git a/backends/cloud/onedrive/onedrivestorage.cpp b/backends/cloud/onedrive/onedrivestorage.cpp new file mode 100644 index 0000000000..b632c74580 --- /dev/null +++ b/backends/cloud/onedrive/onedrivestorage.cpp @@ -0,0 +1,151 @@ +/* ScummVM - Graphic Adventure Engine +* +* ScummVM is the legal property of its developers, whose names +* are too numerous to list here.
