Function documentation

BoostZ()

 ========== Constructors and Assignment =====================

Default constructor (identity transformation)

explicit BoostZ(Scalar beta_z)

Construct given a Scalar beta_z

{ SetComponents(beta_z); }

void Rectify()

 The compiler-generated copy ctor, copy assignment, and dtor are OK.

Re-adjust components to eliminate small deviations from a perfect
orthosyplectic matrix.

SetComponents(ROOT::Math::BoostZ::Scalar beta_z)

 ======== Components ==============

Set components from a Scalar beta_z

Scalar Beta()

Retrieve the beta of the Boost

{ return fBeta; }

Scalar Gamma()

Retrieve the gamma of the Boost

{ return fGamma; }

void SetBeta(ROOT::Math::BoostZ::Scalar beta)

Set the given beta of the Boost

{ SetComponents(beta); }

GetLorentzRotation(ROOT::Math::BoostZ::Scalar* r) const

Get elements of internal 4x4 symmetric representation, into a data
array suitable for direct use as the components of a LorentzRotation
Note -- 16 Scalars will be written into the array; if the array is not
that large, then this will lead to undefined behavior.

operator()(const ROOT::Math::LorentzVector<ROOT::Math::PxPyPzE4D<double> >& v) const

 =========== operations ==============

Lorentz transformation operation on a Minkowski ('Cartesian')
LorentzVector

A4Vector operator*(const ROOT::Math::LorentzVector<ROOT::Math::PxPyPzE4D<double> >& v) const

Overload operator * for boost on a vector
