Detailed Description

Utility class to handle the creation of the Auxiliary measurement used in an Acts track fit This class declares the additionally written xAOD::AuxiliaryMeasurementContainers to the AvalancheScheduler.

Per event, the user creates an instance of the MeasurementProvider which setups the storage backend for the measurements and writes the containers to StoreGate. Auxiliary measurements are created by calling the newMeasurement method.

template<class PropOwner >

ActsTrk::AuxiliaryMeasurementHandler::AuxiliaryMeasurementHandler

(

PropOwner *

owner

)

Constructor taking the pointer to the class holding the object used to declare the data dependency from the WriteHandleKeys to the AvalancheScheduler.

The object should be defined in the header like ActsTrk::AuxiliaryMeasurementHandler m_pseudoHandle{this};

makeHandle()

AuxiliaryMeasurementHandler::MeasurementProvider ActsTrk::AuxiliaryMeasurementHandler::makeHandle	(	const EventContext &	ctx,
		xAOD::TrackSurfaceContainer &	surfaceBackend
	)		const

Creates a new MeasurementProvider and triggers the write of the container backend to StoreGate.

The user needs to provide a reference to a mutable xAOD::TrackSurfaceContainer where the persistified surfaces are appended to. The client needs to ensure that the lifetime of the surface container prevails the provider's lifetime.

Parameters

ctx	EventContext to write the containers to store gate
surfaceBackend	Reference to a mutable track surface container.
