LayerTriplets Namespace Reference

Typedefs
using	Layer = SeedingLayerSetsHits::SeedingLayer
using	LayerSet = SeedingLayerSetsHits::SeedingLayerSet
using	LayerSetAndLayers = std::pair< LayerSet, std::vector< Layer > >

Functions
std::vector< LayerSetAndLayers >	layers (const SeedingLayerSetsHits &sets)

Detailed Description

A class grouping pixel layers in pairs and associating a vector of layers to each layer pair. The layer pair is used to generate hit pairs and the associated vector of layers to generate a third hit confirming layer pair
