Detailed Description

A volume builder to be used for building concentric cylinder volumes.

• a) configured volume
• b) wrapping around a cylindrical/disk layer config

All are optionally wrapped around a given volume which has to by a cylinder volume and which has to be center at z == 0

To receive the tracking volume it is possible to also hand over a triple of layers, which is a C++ tuple of three pointers to layer vectors (defined in the ITrackingVolumeBuilder). This functionality is needed for a possible translation of an geometry existing in another format. The first entry represents the layers of the negative endcap, the second the layers of the barrel and the third the layers of the positive endcap. If the one of these pointers is a nullptr no layers will be created for this volume

For the endcap region it is possible to check for a ring layout, in which case an attempt to split into individual ring volumes is done

Member Function Documentation

analyzeContent()

VolumeConfig Acts::CylinderVolumeBuilder::analyzeContent	(	const GeometryContext &	gctx,
		const LayerVector &	lVector,
		const MutableTrackingVolumeVector &	mtvVector ) const

Analyze the config to gather needed dimension.

Parameters

[in]	gctx	the geometry context for this building
[in]	lVector	is the vector of layers that are parsed
[in]	mtvVector	Vector of mutable tracking volumes to analyze

Returns

a VolumeConfig representing this layer

getConfiguration()

(

)

const

Get configuration method.

Return the configuration object.

Returns

a copy of the config object

setConfiguration()

void Acts::CylinderVolumeBuilder::setConfiguration

(

const Config &

cvbConfig

)

Set configuration method.

Parameters

[in]

cvbConfig

is the new configuration to be set

setLogger()

void Acts::CylinderVolumeBuilder::setLogger

(

std::unique_ptr< const Logger >

newLogger

)

set logging instance

Parameters

[in]

overridevirtual

CylinderVolumeBuilder main call method.

Parameters

[in]	gctx	geometry context for which this cylinder volume is built
[in]	existingVolume	is an (optional) volume to be included
[in]	externalBounds	are (optional) external confinement constraints

Returns

a mutable pointer to a new TrackingVolume which includes the optionally provided existingVolume consistently for further processing
