Function Documentation

void TOFEstimators::init

(

)

Called at the begin of the job before anything is read.

Extracts geometry details and initializes Kalman Filter System.

Definition at line 76 of file TOFEstimators.cc.

marlin::Processor* TOFEstimators::newProcessor ( )

inline

Method required by the Marlin to register processor in the global scope.

Definition at line 37 of file TOFEstimators.h.

TOFEstimators& TOFEstimators::operator= ( const TOFEstimators &  )

delete

Copy assignment operator.

We remove it to avoid W-effc++ warnings.

void TOFEstimators::processEvent

(

EVENT::LCEvent *

evt

)

Called for every event - the working horse.

Calculates momentum, track length and time of flight and writes them into PIDHandler of the input collection object.

Definition at line 98 of file TOFEstimators.cc.

TOFEstimators::TOFEstimators ( const TOFEstimators &  )

delete

Copy constructor.

We remove it to avoid W-effc++ warnings.

TOFEstimators::TOFEstimators

(

)

Default constructor.

Registers steering parameters from the xml steering file.

Definition at line 37 of file TOFEstimators.cc.
