Classes
class	All_locks_iterator
	Iterates over all locks in the lock sys in a manner which guarantees that all locks from the same lock queue are processed in a single critical section. More...

Functions
const lock_t *	locksys::find_blockers (const lock_t &wait_lock, std::function< bool(const lock_t &)> visitor)
	Calls visitor for each lock_t object which is a reason that wait_lock has to wait. More...

void	locksys::find_on_table (const table_id_t table_id, std::function< bool(const lock_t &)> visitor)
	A helper method to access dict_table_t::locks list in a way which is safe against the case another thread is trying to drop or truncate the table. More...
