virtual void ZMassConstraint::IConstraintFit::addFSRParticle	(	const xAOD::IParticle &	part,
		const TLorentzVector &	fsr4Vec,
		ConstraintFitInput &	input
	)			[pure virtual]

Add in FSR photon to input, must provide BOTH the IParticle AND 4vec of FSR photon The IParticle is used to identify type of particle: electron/unconverted photon/converted photon

Implemented in ZMassConstraint::ConstraintFit.

virtual StatusCode ZMassConstraint::IConstraintFit::doMassFit	(	const ConstraintFitInput &	input,
		ConstraintFitOutput &	output
	)			[pure virtual]

Declare the interface that the class provides.

Perform the constrained mass fit

Implemented in ZMassConstraint::ConstraintFit.

virtual double ZMassConstraint::IConstraintFit::getMassError	(	const ConstraintFitOutput &	fitOutput,
		const ConstraintFitInput &	extraInput = ConstraintFitInput()
	)			[pure virtual]

Calculate the mass error with the result of fit and possible additional input (4-vecs/cov mat) that has NOT been fit

Implemented in ZMassConstraint::ConstraintFit.
