From bb207ae513ef02bfaf8e76374af40419a20742fe Mon Sep 17 00:00:00 2001 From: Alexander Tkachev Date: Mon, 6 Jun 2016 20:04:13 +0600 Subject: CLOUD: Add GoogleDriveResolveIdRequest GoogleDriveResolveIdRequest gets a lowercase path and searches for the specified file's id. To do that it lists path's subdirectories one by one with GoogleDriveListDirectoryByIdRequest. GoogleDriveListDirectoryByIdRequest gets a Google Drive id and lists that directory (not recursively). --- .../googledrivelistdirectorybyidrequest.cpp | 144 +++++++++++++++++++++ 1 file changed, 144 insertions(+) create mode 100644 backends/cloud/googledrive/googledrivelistdirectorybyidrequest.cpp (limited to 'backends/cloud/googledrive/googledrivelistdirectorybyidrequest.cpp') diff --git a/backends/cloud/googledrive/googledrivelistdirectorybyidrequest.cpp b/backends/cloud/googledrive/googledrivelistdirectorybyidrequest.cpp new file mode 100644 index 0000000000..0915b623f3 --- /dev/null +++ b/backends/cloud/googledrive/googledrivelistdirectorybyidrequest.cpp @@ -0,0 +1,144 @@ +/* ScummVM - Graphic Adventure Engine +* +* ScummVM is the legal property of its developers, whose names +* are too numerous to list here.
