Detailed Description

The LayerArrayCreator is a simple Tool that helps to construct LayerArrays from std::vector of Trk::CylinderLayer, Trk::DiscLayer, Trk::PlaneLayer.

The input layers are

It fills the gaps automatically with Trk::NavigationLayer to be processed easily in the Navigation of the Extrapolation process.

◆ sysInitialize()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysInitialize ( )

Perform system initialization for an algorithm.

We override this to declare all the elements of handle key arrays at the end of initialization. See comments on updateVHKA.

Reimplemented in asg::AsgMetadataTool, AthCheckedComponent< AthAlgTool >, and AthCheckedComponent<::AthAlgTool >.

◆ sysStart()

overridevirtualinherited

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.
