From 2b3caf1efadd2a68384978e77cfceab158c703f3 Mon Sep 17 00:00:00 2001 From: Alexander Tkachev Date: Wed, 13 Jul 2016 14:57:01 +0600 Subject: CLOUD: Add IdStorage This is a special base class for Storages which are using ids instead of paths in their APIs, like Box or Google Drive. This commit makes Box derived from IdStorage. --- backends/cloud/id/idlistdirectoryrequest.cpp | 129 +++++++++++++++++++++++++++ backends/cloud/id/idlistdirectoryrequest.h | 66 ++++++++++++++ backends/cloud/id/idresolveidrequest.cpp | 125 ++++++++++++++++++++++++++ backends/cloud/id/idresolveidrequest.h | 60 +++++++++++++ backends/cloud/id/idstorage.cpp | 86 ++++++++++++++++++ backends/cloud/id/idstorage.h | 73 +++++++++++++++ 6 files changed, 539 insertions(+) create mode 100644 backends/cloud/id/idlistdirectoryrequest.cpp create mode 100644 backends/cloud/id/idlistdirectoryrequest.h create mode 100644 backends/cloud/id/idresolveidrequest.cpp create mode 100644 backends/cloud/id/idresolveidrequest.h create mode 100644 backends/cloud/id/idstorage.cpp create mode 100644 backends/cloud/id/idstorage.h (limited to 'backends/cloud/id') diff --git a/backends/cloud/id/idlistdirectoryrequest.cpp b/backends/cloud/id/idlistdirectoryrequest.cpp new file mode 100644 index 0000000000..012065dc77 --- /dev/null +++ b/backends/cloud/id/idlistdirectoryrequest.cpp @@ -0,0 +1,129 @@ +/* ScummVM - Graphic Adventure Engine +* +* ScummVM is the legal property of its developers, whose names +* are too numerous to list here.
