template<typename Data >

WSharedObjectTicketWrite< Data >::WSharedObjectTicketWrite ( Data &  data, boost::shared_ptr< boost::shared_mutex >  mutex, boost::shared_ptr< WCondition >  condition  )

inlineprotected

Create a new instance.

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

Parameters:
