Utility class for kinematical transformations of KVParticle class.

Created by KVClassFactory on Thu Jan 19 15:37:43 2017 Author: John Frankland,,,

This class is used as a generic argument for the KVEvent::SetFrame() and KVParticle::SetFrame() methods (amongst others).

It is not always necessary to explicitly use this class when calling these methods. Any class for which a single-argument KVFrameTransform constructor is defined can be used, even a temporary (unnamed) object:

e.g. for KVParticle::SetFrame(const Char_t* frame, const KVFrameTransform& ft) the following calls are valid:

KVParticle p;
TVector3 boost(0,0,3.0);// in cm/ns
p.SetFrame("toto", boost);
p.SetFrame("toto", TVector3(0,0,3.0)); // same effect as previous
TRotation rot;
rot.RotateZ(TMath::PiOver2()); // 90 deg. rotation around beam
p.SetFrame("titi", rot);

On the other hand, when more than one argument to the KVFrameTransform constructor is required, before C++11 you had to explicitly call the constructor in question, although once again it is sufficient to use a temporary object in the method call:

p.SetFrame("tata", KVFrameTransform(TVector3(0,0,0.1),kTRUE));
 --> boost to frame moving at 0.1c in beam direction
 
p.SetFrame("tutu", KVFrameTransform(rot, TVector3(0,0,0.1), kTRUE));
 --> rotation around beam axis followed by boost 0.1c

With C++11 this becomes

p.SetFrame("tata", {TVector3(0,0,0.1),kTRUE});
 --> boost to frame moving at 0.1c in beam direction
 
p.SetFrame("tutu", {rot, TVector3(0,0,0.1), kTRUE});
 --> rotation around beam axis followed by boost 0.1c

Note: for boosts, default units are cm/ns; for rotations (TRotation), default units are radians
