Detailed Description

Collection of static helper functions for reading and writing data with SIO.

Could go to the SIO_functions class. Also defines some constant names for lcio-SIO.

std::string SIO::LCSIO::getValidSIOName ( const std::string &  aName )

static

Creates a valid SIO name (basically equivalent to a valid C++ name) by replacing every [.

], [] and [/] with underscores and removing all nonalphanumeric characters and adding an 'A' to the beginning, if necessary.

Referenced by SIO::SIOReader::open(), and SIO::SIOWriter::open().

unsigned int SIO::LCSIO::read ( SIO_stream *  stream, char **  c, int *  len = 0  )

static

Read a string from the stream into a dummy buffer.

Warning the same buffer is used for each call. So the return value needs to be copied to its final memory destination. len holds the length of the string (can contain '\0').

void SIO::LCSIO::seekStream ( SIO_stream *  stream, EVENT::long64  pos  )

static

Seek stream to the given absolute position - if pos<0 from end of file.

Exceptions

IOException

Referenced by SIO::LCIORandomAccessMgr::createEventMap(), SIO::SIOWriter::open(), SIO::LCIORandomAccessMgr::readLCIOIndexAt(), SIO::LCIORandomAccessMgr::readLCIORandomAccessAt(), and SIO::LCIORandomAccessMgr::recreateEventMap().

unsigned int SIO::LCSIO::write ( SIO_stream *  stream, int  i  )

static

This version checks the versionId to be able to read 'old' files with trailing '\00' (version <= 00-02).

Remove this method after a reasonable transition period...Write an int to the stream.

unsigned int SIO::LCSIO::write ( SIO_stream *  stream, EVENT::long64  i  )

static

Write a vector size to the stream (needed for AMD64 architectures)

Write a 64bit integer to the stream

unsigned int SIO::LCSIO::write ( SIO_stream *  stream, const std::string &  s  )

static

Write a string to the stream.

Writes the length of the string first and adds '\0' to the end.
