Constructor & Destructor Documentation

◆ MsgHandler()

MsgHandler ( int complevel = 0 )

explicit

Constructor.

Parameters

complevel Compression level and algorithm: algorithm*100 + level where algorithm can be one of 0: default root system algorithm (usually zlib) 1: zlib 2: lzma 3: old root compression code and level can be between 1 and 9 (0 disables compression). So for example 101 corresponds to zlib with minimal compression while 209 means lzma with maximal compression.

◆ encode_msg()

EvtMessage * encode_msg ( ERecordType rectype )

virtual

Stream object list into an EvtMessage.

Caller is responsible for deletion.

Member Data Documentation

◆ m_complevel

int m_complevel

private

compression algorithm * 100 + compression level.

level can be 0 for no compression to 9 for highes compression, algorithm can be one of default (0), zlib (1) or lzma (2)
