std::shared_ptr< TriggerResults > EventSelector::maskTriggerResults ( TriggerResults const & inputResults )

Applies a trigger selection mask to a specified trigger result object. Within the trigger result object, each path status is left unchanged if it satisfies the trigger selection (path specs) or cleared if it does not satisfy the trigger selection. In this way, the resulting trigger result object contains only path status values that "pass" the selection criteria.

Parameters

inputResults The raw trigger results object that will be masked.

Returns: a copy of the input trigger results object with only the path status results that match the trigger selection.

Exceptions

edm::Exception if the number of paths in the TriggerResults object does not match the specified full trigger list, or if the trigger selection is invalid in the context of the full trigger list.

bool EventSelector::selectionIsValid	(	Strings const &	pathspec,
		Strings const &	fullTriggerList
	)

static

Tests if the specified trigger selection list (path spec) is valid in the context of the specified full trigger list. Each element in the selection list is tested to see if it possible for some combination of trigger results to satisfy the selection. If all selection elements can be satisfied one way or another, then this method returns true. If one or more selection elements could never be satisfied given the input full trigger list, then this method returns false. At some level, this method tests whether the selection list is a "subset" of the full trigger list.

Parameters

pathspec	The trigger selection list (vector of string).
fullTriggerList	The full list of trigger names (vector of string).

Returns: true if the selection list is valid, false otherwise.

Tests if the specified trigger selection lists (path specs) overlap, where "overlap" means that a valid trigger result (given the full trigger list) could satisfy both selections.

Parameters

pathspec1	The first trigger selection list (vector of string).
pathspec2	The second trigger selection list (vector of string).
fullTriggerList	The full list of trigger names (vector of string).

Returns: OverlapResult which indicates the degree of overlap.
