| bool StKinkMaker::acceptTrack | ( | StTrack * | trk | ) | [protected] |
Track acceptance filter fittingMethod() as defined in pams/global/inc/StTrackMethod.h (values themselves are defined in pams/global/inc/StTrackDefinitions.h) while mUseTracker is defined as SetTrackerUsage(). Note that TPT tracks are set as kHelix3DIdentifier BUT, we also found that there are some cases (untraced) where the mEncodedMethod is reset to 0 (the only tracks having kHelix3DIdentifier being tracks with SVT points). So, we had to revert to a non-equality for safety purposes i.e. kTrackerUseTPT will consider any tracks not being kITKalmanFitId (sad).
Julien : I change this on Jerome's request : now TPT tracks will only be kHelix3DIdentifier... for safety purposes too ;-))

| Int_t StKinkMaker::Init | ( | ) | [virtual] |
Init() will aslo initialize the track type to select on. See SetTrackerUsage(). Note that the steering of how to call SetTrackerUsage() is done through StBFChain and the maker m_Mode mechanism. Refer to SetTrackerUsage() method for more explaination.
Reimplemented from StMaker.

| Int_t StKinkMaker::Make | ( | ) | [virtual] |
The Make() method is the one responsible for calling the maker's InitRun(). Note that that InitRun() is called for real data and if both of the following are true
- a header exists
- the run number changes
This is the ONLY place calling the InitRun() routine.

| void StKinkMaker::SetTrackerUsage | ( | Int_t | opt = 0 |
) | [virtual] |
Sets the tracker track-selection flag according to convention defined enumeration in StV0FinderMaker.h . One should not confuse this value with the value of the controlling parameter m_Mode setting calling this method as follow
m_Mode=0 00 Leaves mUseTracker as default i.e. kTrackerUseBOTH (see ctor) m_Mode=1 01 sets mUseTracker to kTrackerUseTPT m_Mode=2 10 Sets mUseTracker to kTrackerUseITTF m_Mode=3 11 Sets mUseTracker to kTrackerUseBOTH (bitmask)
See Init() for how this is set. The m_Mode convention would allow for easier extension to yet another track-selection flags.
