Typedefs
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
typedef lcio::long64	LCCDTimeStamp
	The timestamp in LCCD is a 64bit int as defined in LCIO.

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. More...
LCCDTimeStamp	fromSimpleTime (const 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.

Variables
LCCDTimeStamp	LCCDMinusInf = -9223372036854775807LL - 1
	The smallest possible time stamp.
LCCDTimeStamp	LCCDPlusInf = 9223372036854775807LL
	The largest possible time stamp.
std::string	DBSINCE = "DBSince"
	String constant: DBSince.
std::string	DBTILL = "DBTill"
	String constant: DBTill.
std::string	DBQUERYTIME = "DBQueryTime"
	String constant: DBQueryTime.
std::string	DBINSERTIONTIME = "DBInsertionTime"
	String constant: DBInsertionTime.
std::string	DBTAG = "DBTag"
	String constant: DBTag.
std::string	DBFOLDER = "DBFolder"
	String constant: DBFolder.
std::string	DBNAME = "DBName"
	String constant: DBName.
std::string	DBLAYER = "DBLayer"
	String constant: DBLayer.
std::string	DBTIMESTAMP = "DBTimeStamp"
	String constant: DBTimeStamp.

Detailed Description

The only namespace in the project.

Provides global constants.

Function Documentation

std::string lccd::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.
