Detailed Description

This class manages the lookup for the properties in PropertyStore. It works in two mode: Cancellable mode and Non-Cancellable mode. Non-Cancellable Mode:

• FastFinishLookup() has no-op in this mode.
• Done() will be called whenever lookup finishes and calls the done callback based on sucess of the lookup.
• DeleteWhenDone() will delete the callback if Done() is already called or set the bit so that callback delete itself after executing Done(). Cancellable Mode:
• FastFinishLookup() will call the done callback if its not yet called.
• Done() is same as that in non-cancellable mode but if FastFinishLookup() is called then it will not call the done callback.
• DeleteWhenDone() works same as it works in non-cancellable mode.

bool net_instaweb::PropertyStoreGetCallback::AddPropertyValueProtobufToPropertyPage	(	const PropertyCache::Cohort *	cohort,
		const PropertyValueProtobuf &	pcache_value,
		int64	min_write_timestamp_ms
	)

Add the given property cache value to the PropertyPage if PropertyPage is not NULL. Returns true if PropertyValueProtobuf is successfully added to PropertyPage.

void net_instaweb::PropertyStoreGetCallback::Done

(

bool

success

)

Done is called when lookup is finished. This method is made public so that PropertyStore implementations may call it.

virtual void net_instaweb::PropertyStoreGetCallback::FastFinishLookup ( )

virtual

Try to finish all the pending lookups if possible and call Done as soon as possible.

Implements net_instaweb::AbstractPropertyStoreGetCallback.
