Constructor & Destructor Documentation

net_instaweb::CachePropertyStore::CachePropertyStore	(	const GoogleString &	cache_key_prefix,
		CacheInterface *	cache,
		Timer *	timer,
		Statistics *	stats,
		ThreadSystem *	thread_system
	)

Does not take the ownership of cache, timer and stats object. L2-only caches should be used for CachePropertyStore. We cannot use the L1 cache because this data can get stale quickly.

Member Function Documentation

void net_instaweb::CachePropertyStore::AddCohortWithCache	(	const GoogleString &	cohort,
		CacheInterface *	cache
	)

Establishes a Cohort to be backed by the specified CacheInterface. Does not take the ownership of cache.

GoogleString net_instaweb::CachePropertyStore::CacheKey	(	const StringPiece &	url,
		const StringPiece &	options_signature_hash,
		const StringPiece &	cache_key_suffix,
		const PropertyCache::Cohort *	cohort
	)		const

Gets the underlying key associated with cache_key and a Cohort. This is the key used for the CacheInterface provided to the constructor. This is made visible for testing, to make it possible to inject delays into the cache via DelayCache::DelayKey.

virtual void net_instaweb::CachePropertyStore::Get ( const GoogleString &  url, const GoogleString &  options_signature_hash, const GoogleString &  cache_key_suffix, const PropertyCache::CohortVector &  cohort_list, PropertyPage *  page, BoolCallback *  done, AbstractPropertyStoreGetCallback **  callback  )

virtual

Cache lookup is initiated for the given cohort and results are populated in PropertyPage if it is valid. callback parameter can be set to NULL if cohort_list is empty.

Implements net_instaweb::PropertyStore.

virtual GoogleString net_instaweb::CachePropertyStore::Name ( ) const

virtual

The name of this PropertyStore – used for logging and debugging.

It is strongly recommended that you provide a static GoogleString FormatName(...) method for use in formatting the Name() return, and in testing, e.g. in third_party/pagespeed/system/system_caches_test.cc.

Implements net_instaweb::PropertyStore.
