Detailed Description

template<class ACE_LOCK>
class ACE_Locked_Data_Block< ACE_LOCK >

A Data_Block with a concrete locking strategy.

Data_Blocks can be parametric on the kind of lock they use; in many cases the lifetime of the lock is tied to the lifetime of the Data_Block itself. But since Data_Blocks are reference counted it is hard for users to control the lock lifetime. This class is parametric over the kind of lock used.
