Detailed Description

Logging into dirfile with buffer in memory.

Dirfile is a special format used by the kst program. See documentation of kst for description.

This format is used to store scalars, hence multivariate RVs must be separated.

Constructor & Destructor Documentation

bdm::dirfilelog::dirfilelog	(	std::string	dirname0,
		int	maxlen0
	)			[inline]

Default constructor.

Parameters:

	dirname0	name of the directory in which to store the results
	maxlen0	length of the memory buffers, when full the buffers will be dumped to HDD and returned to the beginning.

Member Function Documentation

virtual int bdm::logger::add	(	const RV &	rv,
		string	name = ""
	)			[inline, virtual, inherited]

returns an identifier which will be later needed for calling the logit() function For empty RV it returns -1, this entry will be ignored by logit().

References bdm::RV::_dsize(), bdm::logger::entries, and bdm::logger::names.

void bdm::dirfilelog::write_buffers

(

int

Len

)

Write memory storage to disk.

Parameters:

Len

length of buffer to be written, if 0 the file is truncated at 0.

References dirname, bdm::logger::entries, bdm::memlog::maxlen, scalarnames, and bdm::memlog::vectors.

Referenced by finalize(), init(), and step().
