ACE_Locked_Data_Block(3)

NAME

ACE_Locked_Data_Block - A Data_Block with a concrete locking strategy.

SYNOPSIS

#include <ace/Message_Block_T.h>
template<class ACE_LOCK>
class ACE_Locked_Data_Block : public ACE_Data_Block
{
  public:
    ACE_Locked_Data_Block (void);
    ACE_Locked_Data_Block (

        ACE_Message_Block::ACE_Message_Type msg_type,
        const char *msg_data,
        ACE_Allocator *allocator_strategy,
        ACE_Message_Block::Message_Flags flags,
        ACE_Allocator *data_block_allocator
        );
    virtual ~ACE_Locked_Data_Block (void);
    virtual ACE_Data_Block *clone_nocopy (
        ACE_Message_Block::Message_Flags mask = 0
        ) const;
  private:
    ACE_LOCK lock_;
    inline ACE_UNIMPLEMENTED_FUNC (
        ACE_Locked_Data_Block<ACE_LOCK> &operator= (const ACE_Locked_Data_Block<ACE_LOCK> &)
        );
};

DESCRIPTION

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.

Initialization and termination methods.

ACE_Locked_Data_Block (void);

ACE_Locked_Data_Block (
    size_t size,
    ACE_Message_Block::ACE_Message_Type msg_type,
    const char *msg_data,
    ACE_Allocator *allocator_strategy,
    ACE_Message_Block::Message_Flags flags,
    ACE_Allocator *data_block_allocator
    );

virtual ~ACE_Locked_Data_Block (void);

virtual ACE_Data_Block *clone_nocopy (
    ACE_Message_Block::Message_Flags mask = 0
    ) const;

Disallow these operations.
