/*! \class PIBinaryLog
|
|
* \brief Class for read and write binary data to logfile, and playback this data in realtime, or custom speed
|
|
*
|
|
* \section PIBinaryLog_sec0 Synopsis
|
|
* Binary Log is a file with simple header, where you can read and write some binary data.
|
|
* Any written data include special header with ID, size and timestamp.
|
|
* This header provides separation different messages from the one file by choosing different IDs.
|
|
* With \a filterID or special functions, like \a readBinLog() you can choose IDs what you want to read.
|
|
* With function \a writeBinLog() or \a setDefaultID() you can choose ID that mark you data.
|
|
* By default ID = 1, and \a filterID is empty, that mean you read any ID without filtering.
|
|
* ThreadedRead provide you playback data, with delay that you write data.
|
|
* You can choose different playbak modes by set \a PlayMode.
|
|
*
|
|
* \section PIBinaryLog_sec1 Basic usage
|
|
* This class provide all functions of \a PIIODevice, such \a open(), \a close(),
|
|
* \a read() ,\a write(), and threaded read/write.
|
|
* function \a setLogDir() need to set directory for BinLog files
|
|
* function \a createNewFile() need to create new binlog file
|
|
* function \a restart() need start from the begining of binlog file
|
|
*
