Member Function Documentation

const bool cscdqm::Dispatcher::getHisto	(	const HistoDef &	histoD,
		MonitorObject *&	me
	)

Global get MO function. If request has reached this function it means that histo is not in cache!

Parameters:

histoD	Histogram Definition to get
me	MO to return

Returns:: true if me found and filled, false - otherwise

For the first DDU - book general

For the first and specific CSCs - book general and specific

cache.printContent();

For the Parameters - book parameter histogram

If not found after booking - mark it as not existent
