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.
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.
