Detailed Description

An Interface for hits.

They have of course a position, accessible with getX(), getY() and getZ().

Also a hit has a sector. A sector is just an integer, telling where the hit lies. For example a sector 141 could mean 1st layer, 4th module, 1st sensor. But how information is encoded is dealt with in the SectorSystem classes (see ISectorSystem for the Abstract Base Class ).

Member Function Documentation

float IHit::distTo

(

IHit *

otherHit

)

Returns

the distance to an other hit

References getX(), getY(), and getZ().

double KiTrack::IHit::get3DAngle ( IHit *  otherHit ) const

inline

to be used with mini-vectors:

Returns

3D angle

unsigned KiTrack::IHit::getLayer ( ) const

inline

Returns

the layer of the hit

References KiTrack::ISectorSystem::getLayer(), and getSectorSystem().

double KiTrack::IHit::getPhi ( ) const

inline

to be used with mini-vectors:

Returns

azimuth angle
