From 7d37d296f942ac993d041b4576ed52265170c4a8 Mon Sep 17 00:00:00 2001 From: Alexey Rusakov Date: Sun, 2 Jan 2022 06:03:26 +0100 Subject: Add ImplPtr and makeImpl The original (more complex and comprehensive) solution belongs to https://oliora.github.io/2015/12/29/pimpl-and-rule-of-zero.html - this commit only provides a small wrapper for non-copyable Private class implementations common throughout libQuotient. Unlike the original, default initialisation is made explicit - you have to pass ZeroImpl() instead (and I firmly believe it's a good thing: normally pointers to Private should not remain nullptr). The reason ZeroImpl<> is not a template variable is quite simple: unique_ptr is non-copyable and so cannot be initialised from; while a template function will initialise the value in-place thanks to copy elision. --- lib/jobs/downloadfilejob.h | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'lib/jobs/downloadfilejob.h') diff --git a/lib/jobs/downloadfilejob.h b/lib/jobs/downloadfilejob.h index 9e807fe7..f8c62e4b 100644 --- a/lib/jobs/downloadfilejob.h +++ b/lib/jobs/downloadfilejob.h @@ -13,13 +13,12 @@ public: DownloadFileJob(const QString& serverName, const QString& mediaId, const QString& localFilename = {}); - ~DownloadFileJob() override; QString targetFileName() const; private: class Private; - QScopedPointer d; + ImplPtr d; void doPrepare() override; void onSentRequest(QNetworkReply* reply) override; -- cgit v1.2.3
