Detailed Description

Consumes a set of Run 3 trigger navigation collection(s), applies slimming/thinning, writes out a single output collection.

Operations include:

• Keeping graph nodes which correspond to a particular set of chains. Good for small dAOD sizes.
• Keeping only the bottom of the graph, from the final "feature" onward. Good for physics analysis / trigger matching.
• Keeping failed branches. Used for trigger performance studies / T0 monitoring.
• Removing named nodes from the graph, ("F"ilter nodes are only used online).
• Removing named edges from the graph, ("view" edges are only used online).

createL1GraphNodes()

StatusCode TrigNavSlimmingMTAlg::createL1GraphNodes ( Outputs &  outputContainers ) const

Creates two new graph node from scratch, populates it using the TriggerDecisionTool with the hash of the item names L1 items which passed before prescale and after veto.

This makes available L1 trigger is-passed data in the same format as used for HLT navigation. This creates two nodes which were never made at P1 during Run 3.

Parameters

[out]

output

Pointer to the Decision object ptr in the output collection.

createPresaledGraphNode()

StatusCode TrigNavSlimmingMTAlg::createPresaledGraphNode ( Outputs &  outputContainers, const TrigCompositeUtils::DecisionIDContainer &  chainIDs  ) const

private

Creates a new graph node from scratch, populates it with the Chain IDs of all HLT chains which were not run in this event due to application of HLT prescales.

The data are read from the trigger bits using the TrigDecisionTool. This re-creates a node which is available at P1 in Run 3, but which was never persisted into the online slimmed navigation.

Parameters

[out]	output	Pointer to the Decision object ptr in the output collection.
[in]	chainIDs	DecisionIDs are used to filter the output DecisionObjects.

propagateSeedingRelation()

StatusCode TrigNavSlimmingMTAlg::propagateSeedingRelation ( const TrigCompositeUtils::NavGraphNode *  inputNode, IOCacheMap &  cache, const EventContext &  ctx  ) const

Copy the subset of "seed" links which are present in the inputNode.

This function uses the IOCacheMap to perform all linking only against the mutable Decision objects which form the slimmed and thinned navigation. It must only be called after inputToOutput has been used to create all of the output Decision objects.

Parameters

[in]	inputNode	The thinned transient NavGraphNode which only now has seed links which we want to keep
[in,out]	cache	Cached mapping of input->output objects.
[in]	ctx	Event context.
