detectorType()

DetectorType ActsTrk::AlignableGeoPositioning::detectorType

(

)

const

returns the detector type of the cache

{ return m_type; }

fetchTransform()

protectedpure virtual

Implemented in ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< CachingDetectorEle >, ActsTrk::ReadoutSurfacePositioning< ActsDetectorElement >, ActsTrk::ReadoutSurfacePositioning< ActsDetectorElement >, ActsTrk::ReadoutSurfacePositioning< ActsDetectorElement >, ActsTrk::ReadoutSurfacePositioning< ActsDetectorElement >, ActsTrk::ReadoutSurfacePositioning< ActsDetectorElement >, ActsTrk::ReadoutSurfacePositioning< ActsDetectorElement >, ActsTrk::ReadoutSurfacePositioning< ActsDetectorElement >, and ActsTrk::VolumePlacement::VolumeGeoPositioning.

getTransform() [1/3]

const Amg::Transform3D & ActsTrk::AlignableGeoPositioning::getTransform

(

const Acts::GeometryContext &

tgContext

)

const

returns the cached transform from the Acts Geometry context

Parameters

tgContext

The geometry context to be unpacked to the ATLAS geometry context

getTransform() [2/3]

const Amg::Transform3D & ActsTrk::AlignableGeoPositioning::getTransform

(

const DetectorAlignStore *

store

)

const

Returns the matching transformation from the alignment store.

If a nullptr is given, then it's equivalent to the case that the transformation is pointing to a perfectly aligned surface. In this case, the internal nominal transformation cache is invoked.

Parameters

store

Pointer to the detector aligment store

getTransform() [3/3]

const Amg::Transform3D & ActsTrk::AlignableGeoPositioning::getTransform

(

const GeometryContext &

gctx

)

const

returns the cached transform from the Acts Geometry context

Parameters

gctx	The geometry context holding the aligned transforms

hash()

IdentifierHash ActsTrk::AlignableGeoPositioning::hash

(

)

const

Returns the sensor hash of this transformation cache.

operator=() [1/2]

AlignableGeoPositioning & ActsTrk::AlignableGeoPositioning::operator= ( AlignableGeoPositioning & other )

deletenoexcept

Delete the move assignment operator.

operator=() [2/2]

AlignableGeoPositioning & ActsTrk::AlignableGeoPositioning::operator= ( const AlignableGeoPositioning & other )

deletenoexcept

Delete the copy assignment operator.

releaseNominalCache()

void ActsTrk::AlignableGeoPositioning::releaseNominalCache ( ) const

virtual

resets the nominal cache associated with the detector element

Reimplemented in ActsTrk::IReadoutSurfacePositioning.

Definition at line 22 of file TransformCache.cxx.

                                                            {
        m_nomCache.release();
    }

storeTransform()

bool ActsTrk::AlignableGeoPositioning::storeTransform

(

DetectorAlignStore &

store

)

const

Store the final transform in the mutable alignment store.

Returns true whether a new transform was stored

Parameters

store

The reference to the store where the cache stores its transform

Definition at line 26 of file TransformCache.cxx.

                                                                                {
