varPointer to log variable
namename of the log variable
grouplogger group the variable belongs to
unitunit of the log variable
dividerdivider is defining the update frequency of the logger element (ctrl_freq/divider)
actionlog action of the log variable
bufferSizesize of the buffer storing log elements
bufferTypedetermines the buffer type

◆ initTimeLogElement()

virtual void signal_logger_std::SignalLoggerStd::initTimeLogElement ( )

Initializes the pointer to the logelement

Reimplemented from signal_logger::SignalLoggerBase.

◆ workerSaveData()

virtual bool signal_logger_std::SignalLoggerStd::workerSaveData ( const std::string &  logFileName,
const signal_logger::LogFileTypeSet logfileTypes 

Save all the buffered data into a log file.

Implements signal_logger::SignalLoggerBase.

Reimplemented in signal_logger_ros::SignalLoggerRos.
