Typedefs
typedef lcio::long64	LCCDTimeStamp
	The timestamp in LCCD is a 64bit int as defined in LCIO.
typedef std::pair< LCCDTimeStamp, LCCDTimeStamp >	ValidityInterval
typedef std::vector< ValidityInterval >	ValidityVector
typedef std::vector< lcio::LCCollection * >	ColVec
	Convenience typedef for vector of LCCollection pointers.
typedef std::map< std::string, IConditionsHandler * >	HandlerMap
typedef std::map< std::string, VCollectionStreamer * >	StreamerMap
Functions
void	ensure_LCCDTimeStamp_is_64bit ()
	If this doesn't compile than LCCDTimeStamp doesn't have 64bit.
std::string	getDBInitString ()
	Returns a database initialization string of the form "DB_HOST:DB_NAME:DB_USER:PASSWD" from the environment variable $LCCD_DB_INIT.
LCCDTimeStamp	fromSimpleTime (SimpleTime st)
	Converts the 64bit time stamp in SimpleTime objects (based on 1.1.1900) to the LCIO definition of time stamps: ns since 1.1.1970 UTC.

Function Documentation

std::string getDBInitString (   )

Returns a database initialization string of the form "DB_HOST:DB_NAME:DB_USER:PASSWD" from the environment variable $LCCD_DB_INIT. The default value is determined at compile time from the same variable. If it isn't set at compile time "localhost:lccd_test:calvin:hobbes" is used as default-default.
