◆ getISuperLayer()

ISuperLayer getISuperLayer ( ) const

inlineinherited

Returns the common super layer id of all stored tracking hits.

This checks if all items are located in the same superlayer and returns the superlayer id of the later. Returns ISuperLayerUtil::c_Invalid, if the superlayer is not shared among the hits.

Definition at line 57 of file CDCSegment.h.

◆ getStereoKind()

EStereoKind getStereoKind ( ) const

inlineinherited

Returns the common stereo type of all hits.

This checks if all tracking hits are located in the same superlayer and
returns the stereo type of the later. Returns EStereoKind::c_Invalid if the superlayer
is not shared among the tracking hits.

Definition at line 39 of file CDCSegment.h.

◆ receiveMaskedFlag()

void receiveMaskedFlag ( bool fromHits = false ) const

Check all contained wire hits if one has the masked flag.

Set the masked flag of this segment in case at least one of the contained wire hits is flagged as masked.

Definition at line 438 of file CDCSegment2D.cc.

Member Data Documentation

◆ m_automatonCell

AutomatonCell m_automatonCell

mutableprivate

Memory for the automaton cell.

It is declared mutable because it can vary rather freely despite of the hit content might be required fixed.
