Member Function Documentation

detectorType()

DetectorType ActsTrk::TransformCache::detectorType

(

)

const

returns the detector type of the cache

Definition at line 23 of file TransformCache.cxx.

{ return m_type; }

fetchTransform()

virtual Amg::Transform3D ActsTrk::TransformCache::fetchTransform ( const DetectorAlignStore *  store ) const

protectedpure virtual

getTransform()

const Amg::Transform3D& ActsTrk::TransformCache::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.

hash()

IdentifierHash ActsTrk::TransformCache::hash

(

)

const

Returns the sensor hash of this transformation cache.

identify()

virtual Identifier ActsTrk::TransformCache::identify ( ) const

pure virtual

Returns the Identifier of the transform cache.

operator=()

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

delete

parent()

virtual const IDetectorElement* ActsTrk::TransformCache::parent ( ) const

pure virtual

Returns the parent IDetectorElement owning the cache.

releaseNominalCache()

void ActsTrk::TransformCache::releaseNominalCache

(

)

const

resets the nominal cache associated with the detector element

Definition at line 17 of file TransformCache.cxx.

transform()

const Amg::Transform3D& ActsTrk::TransformCache::transform

(

const Acts::GeometryContext &

gctx

)

const

returns the cached transform from the Acts Geometry context
