Constructor & Destructor Documentation

stor::TriggerSelector::TriggerSelector	(	Strings const &	pathspecs,
		Strings const &	names
	)

Obsolete: Initializes TriggerSelector to use edm::EventSelector for selection.

Definition at line 21 of file TriggerSelector.cc.

   :
  useOld_(true)
  {
    acceptAll_=false;
    eventSelector_.reset( new edm::EventSelector(pathspecs,names));
  }

stor::TriggerSelector::TriggerSelector	(	edm::ParameterSet const &	pset,
		Strings const &	triggernames,
		bool	old_ = false
	)

Takes ParameterSet wth TriggerSelector string or EventSelection list, and a list of triggers. if old_ is true, it is forced to use EventSelection.

Definition at line 32 of file TriggerSelector.cc.
