Member Function Documentation

virtual PropertyValue* net_instaweb::AbstractPropertyPage::GetProperty	(	const PropertyCache::Cohort *	cohort,
		const StringPiece &	property_name
	)

pure virtual

Gets a property given the property name. The property can then be mutated, prior to the PropertyPage being written back to the cache.

Implemented in net_instaweb::PropertyPage, and net_instaweb::FallbackPropertyPage.

virtual void net_instaweb::AbstractPropertyPage::UpdateValue	(	const PropertyCache::Cohort *	cohort,
		const StringPiece &	property_name,
		const StringPiece &	value
	)

pure virtual

Updates the value of a property, tracking stability & discarding writes when the existing data is more up-to-date.

Implemented in net_instaweb::PropertyPage, and net_instaweb::FallbackPropertyPage.

virtual void net_instaweb::AbstractPropertyPage::WriteCohort ( const PropertyCache::Cohort * cohort )

pure virtual

Updates a Cohort of properties into the cache. It is a programming error (dcheck-fail) to Write a PropertyPage that was not read first. It is fine to Write after a failed Read.

Implemented in net_instaweb::PropertyPage, and net_instaweb::FallbackPropertyPage.
