Detailed Description

Processor that provides access to conditions data in a Marlin application.

Uses LCCD ConditionsHandler. For every ConditionsHandler you have to specify a line in the steering file. Use MyMarlin -l to get examples for the steering parameters.
The conditions data are added to the event as LCCollections with their name. Optionally IConditionsChangeListener subclasses, e.g. ConditionsMaps can be registered for conditions data 'name', these are updated whenever the data changes.

Input - Prerequisites

none

Output

Collections of conditions data are added to the event.

Parameters

DBCondHandler	Initialization of a conditions database handler
DBFileHandler	Initialization of a conditions db file handler
DBInit	Initialization string for conditions database
DataFileHandler	Initialization of a data file handler
SimpleFileHandler	Initialization of a simple conditions file handler

Member Function Documentation

virtual Processor* marlin::ConditionsProcessor::newProcessor ( )

inlinevirtual

Return a new instance of the processor.

Has to be implemented by subclasses.

Implements marlin::Processor.

void marlin::ConditionsProcessor::processEvent ( LCEvent * evt )

virtual

Called for every run.

Updates all registered conditions handlers and adds the data to the event.

Reimplemented from marlin::Processor.

bool marlin::ConditionsProcessor::registerChangeListener	(	lccd::IConditionsChangeListener *	cl,
		const std::string &	name
	)

static

Registers an IConditionsChangeListener, e.g.

a ConditionsMap with the conditions handler 'name'. Returns true if successfull.
