Public Member Functions
void	init ()
	allocate memory for out- and in- buffers
void	reset_buffer (int out)
	switch pointer bufptr
void	transfer_dest (std::vector< val_t * > &buff, const std::vector< int > &meshinds, container_t *cont)
	adds inbuf values to destination buffers
void	make_requests (reqpair_t arg, apMPIComm *comm)
	initialize MPI_Send and MPI_Recv procedures
void	free_requests (reqpair_t arg, apMPIComm *comm)
	remove initialized mpi-procedures

Public Attributes
val_t *	bufptr
	points at outbuf or inbuf (depending on situation)
val_t *	outbuf
	buffer to send data to another processor
size_t	outsz
	total size of outbuf
size_t	outsz_vec = 0
	size of vectorized (beginning) part of outbuf
val_t *	inbuf
	buffer to receive data from another processor
size_t	insz
	total size of inbuf
size_t	insz_vec = 0
	size of vectorized (beginning) part of inbuf
ptrdiff_t	ind = 0
	scalar index for filling buffers
packer_t	destpack
	packer of pairs 'buffer number - index in buffer array', used to distribute values recieved from other processors: these values are initially received to input buffer, and then recorded to destination buffers buff
