Detailed Description

A thread-safe garbage-collected network disk cache.

This class is thread-safe unlike the original QNetworkDiskCache, thus it can be used from multiple threads simultaneously.

Also, old cache data is automatically removed from the cache in a background thread without blocking. The garbage collection can be also triggered manually via the collectGarbage() slot.

The garbage is collected until cache takes 90% of its maximum size.

Constructor & Destructor Documentation

◆ NetworkDiskCache()

LC::Util::NetworkDiskCache::NetworkDiskCache	(	const QString &	subpath,
		QObject *	parent = `nullptr`
	)

explicit

Constructs the new disk cache.

The cache uses a subdirectory subpath in the network directory of the user cache location.

Parameters

[in]	subpath	The subpath in cache user location.
[in]	parent	The parent object of this cache.
