Detailed Description

Garbage collection for a set of network disk caches.

This GC manager class aids having multiple network disk caches at the same path and running garbage collection periodically on them, but only once per each path.

◆ GetCurrentSize()

QFuture< qint64 > LC::Util::NetworkDiskCacheGC::GetCurrentSize ( const QString & path ) const

Schedules calculation of the path total size.

The calculation is performed asynchronously in a separate thread, and a future object is returned which can be used to be notified when the calculation finishes.

Parameters

[in] path The path which total size should be calculated

Returns: The future object for the asynchronous path size calculation.

◆ Instance()

NetworkDiskCacheGC & LC::Util::NetworkDiskCacheGC::Instance ( )

static

Returns a single global instance of the GC manager.

Returns: The single global instance of the GC manager.

◆ operator=()

NetworkDiskCacheGC& LC::Util::NetworkDiskCacheGC::operator= ( const NetworkDiskCacheGC & )

delete

◆ RegisterDirectory()

Util::DefaultScopeGuard LC::Util::NetworkDiskCacheGC::RegisterDirectory	(	const QString &	path,
		const std::function< int()> &	sizeGetter
	)

Registers the given cache path.

Registers the given path to be collected periodically and returns a guard object that unregisters the path when it is destroyed.

The path stops being collected as soon as the last guard object returned from this method is destroyed.

This function also takes a size getter functor returning the desired cache size for the given path. If the same path is registered multiple times with size getters returning different values, the minimum one is used.

Parameters

[in]	path	The path to register for garbage collection.
[in]	sizeGetter	The functor returning the desired total size of files under the path.

Returns: A guard object unregistering the path when it is destroyed.
