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.

Return an exact "deep copy" of the message, the dynamic type is ACE_Locked_Data_Block<> See the documentation in Message_Block.h for details.

Reimplemented from ACE_Data_Block.
