		boost::shared_ptr< boost::shared_mutex >	mutex,
		boost::shared_ptr< WCondition >	condition
	)		[inline, protected]

Create a new instance.

It is protected to avoid someone to create them. It locks the mutex for read.

Parameters:

data	the data to protect
mutex	the mutex used to lock
condition	a condition that should be fired upon unlock. Can be NULL.

template<typename Data >

const Data& WSharedObjectTicketRead< Data >::get

making it const enforces const correctness for contained types!

Returns:

the data (const!)
