Member Function Documentation

virtual const std::string lccd::ConditionsHandlerBase::name (   )  [inline, virtual]

The name of this conditions handler - used, e.g. as name of the collection in update( lcio::LCEvent* evt ). See also: update( lcio::LCEvent* evt ) Implements lccd::IConditionsHandler.

virtual void lccd::ConditionsHandlerBase::update (  LCCDTimeStamp  timestamp  )  [pure virtual]

Retrieves the new conditions data if required by timestamp. Notifies all registered listeners See implementation classes for details. Implements lccd::IConditionsHandler. Implemented in lccd::DataFileHandler, lccd::DBCondHandler, lccd::DBFileHandler, and lccd::SimpleFileHandler.

virtual void lccd::ConditionsHandlerBase::updateEvent (  lcio::LCEvent *  evt  )  [virtual]

Retrieves the new conditions data if required by evt->getTimestamp() and adds a collection to event with its name. Notifies all registered listeners Implements lccd::IConditionsHandler. Reimplemented in lccd::DataFileHandler.
