Collaboration diagram for FragMP4SharedMemSegment:

Public Member Functions
	FragMP4SharedMemSegment (const char *name, std::size_t n_bytes, bool is_server=false)

virtual std::size_t	getSize ()
	Client: return metadata = the size of the payload (not the maximum size). Uses SharedMemSegment::getMeta.

virtual void	put (std::vector< uint8_t > &inp_payload, void *meta_)
	typecast void to std::size_t

virtual void	put (uint8_t buf_, void meta_)

virtual void	copyMetaFrom (void *meta_)
	Dereference metadata pointer correctly and copy the contents into this memory segment's metadata.

virtual void	copyMetaTo (void *meta_)
	Dereference metadata pointer correctly and copy the contents from this memory segment's metadata.

void	putMuxFrame (MuxFrame *f)

Public Member Functions inherited from SharedMemSegment
	SharedMemSegment (const char *name, std::size_t n_bytes, bool is_server=false)
	Default constructor. More...

virtual	~SharedMemSegment ()
	Default destructor.

void	init ()
	Must be called after construction. Reserves shmem payload and correct metadata (depending on the subclass)

void	close_ ()
	Must be called before destruction. Releases correct amount of metadata bytes (depending on the subclass)

bool	getClientState ()
	Was the shmem acquisition succesfull?

Public Attributes
FragMP4Meta *	meta

Public Attributes inherited from SharedMemSegment
uint8_t *	payload
	Pointer to payload.

std::size_t	n_bytes
	Maximum size of the payload (this much is reserved)

Protected Member Functions
virtual void	serverInit ()
	Uses shmem_open with write rights. used by the constructor if is_server=true. Init with correct metadata serialization.

virtual bool	clientInit ()
	Uses shmem_open with read-only rights. Init with correct metadata serialization.

virtual void	serverClose ()
	Erases the shmem segment. used by the constructor if is_server=true.

virtual void	clientClose ()

Additional Inherited Members
