privateinherited

For a given Decision node from a HypoAlg, extracts type-less identification data on the node's Feature and seeding ROI.

Parameters

[in]	chainLegId	The HLT::Identifer of the chain (leg) we're extracting features for.
[in]	EL	The Decision node from the HypoAlg, expected to have a "feature" link attached to it. Expected to be able to locate a "initialRoI" in its history if RequireUniqueROI=True.
[out]	featureKey	Type-less SG Key hash of the collection hosting the Decision node's feature .
[out]	featureIndex	Index inside the featureKey collection.
[out]	roiKey	Type-less SG Key hash of the collection hosting the Decision node's initial ROI collection.
[out]	roiIndex	Index inside the roiKey collection.
[out]	roiIsFullscan	Flag indicating if the located initial ROI has the FullScan flag enabled. Triggers special behaviour allowing the ROI to satisfy arbitrary multiplicities in an arbitrary number of legs.
[out]	objectRequestsNoMultiplicityCheck	Flag indicating of the DecisionObject requested not be included in the multiplicity computation. Triggers special behaviour allowing the DecisionObject to satisfy arbitrary multiplicities in an arbitrary number of legs.
[in,out]	priorFeaturesMap	Data structure collating for a given feature (key) what the prior features were integrated over all previous steps (value set).
