Detailed Description

Convenient class for setting and retrieving particle id information attached to ReconstructedParticles.

Use one instance of PIDHandler for one LCCollection only. When used for setting particle id information the scope of the PIDHandler must match that of the collection, as the collection parameters are updated automatically when the PIDHandler object goes out of scope. Reads (and updates) the collection parameters PIDAlgorithmTypeName, PIDAlgorithmTypeID and the corresponding ParameterNames_PIDAlgorithmTypeName for every algorithm used.

• read and update the collection parameters PIDAlgorithmTypeName, PIDAlgorithmTypeID and the corresponding ParameterNames_PIDAlgorithmTypeName if they exist.

Member Function Documentation

const ParticleID & UTIL::PIDHandler::getParticleID	(	LCObject *	particle,
		int	algorithmID
	)

Return the (first) ParticleID object for the given algorithm and particle (or cluster) - throws UnknownAlgorithm.

Only use if you know there is only one PID object for the algorithms or if you simply want the most likely PID for this algorithm.

References getParticleIDs().

void UTIL::PIDHandler::setParticleIDUsed	(	IMPL::ReconstructedParticleImpl *	particle,
		int	algorithmID
	)

Set the particleID algorithm that is used for this particle's kinematic variables.

• throws UnknownAlgorithm.
