Static Public Member Functions
static void *	operator new (size_t size)
	new operator "new", which places objects not on a heap, but in one of the memory arenas.

static void	operator delete (void *p)
	new operator "delete", to go with the new version of operator new.

static void *	operator new (size_t size, HDFReplayConfig *&o)
	placement "new", needed for stl.

Public Attributes
vstring	filename
	File name pattern for reading an HDF log, if empty, use previous file.

dueca::TimeTickType	replay_start
	Data point to start reading in the data file, defined in DUECA granules.

Static Public Attributes
static const char *const	classname
	The name of this class.

static const uint32_t	magic_check_number
	a "magic" number, hashed out of the class definition, that will be used to check consistency of the sent objects across the dueca nodes.

Detailed Description

Configuration message for HDF5 logging.

When configured to listen to config messages, the HDF5Replayer can switch files or re-use files when in HoldCurrent mode.

Possible modes of operation:

Spool back in the currently used file; send a HDFReplayConfig event with empty filename.
Close the current file and open an new one, send the appropriate file name.
Replay can also start at a later point in the file; send a non-zero replay_skip, to start the data at the offset tick values specified in the replay skip.

Member Function Documentation

static void * dueca::HDFReplayConfig::operator new ( size_t size )

static

new operator "new", which places objects not on a heap, but in one of the memory arenas.

This to speed up memory management.

void dueca::HDFReplayConfig::packDataDiff	(	::dueca::AmorphStore &	s,
		const HDFReplayConfig &	ref ) const

packs the HDFReplayConfig into amorphous storage.

only differences with a previous object are packed.

dueca::TimeTickType dueca::HDFReplayConfig::replay_start

Data point to start reading in the data file, defined in DUECA granules.

A value of 0 implies starting from the first detected stream data point
