Acts::AnyCharge Class Reference

#include <acts/blob/sPHENIX/Core/include/Acts/EventData/Charge.hpp>

Public Member Functions
	AnyCharge ()=delete
	Delete default constructor to ensure charge is always explicitely given.
template<typename T >
constexpr	AnyCharge (T absQ) noexcept
	Construct with the magnitude of the input charge.
template<typename T >
constexpr T	extractCharge (T qOverP) const noexcept
template<typename T >
constexpr T	extractMomentum (T qOverP) const noexcept

Private Attributes
float	m_magnitude

Friends
constexpr bool	operator== (AnyCharge lhs, AnyCharge rhs) noexcept
	Compare for equality.

Detailed Description

Charge and momentum interpretation for arbitrarily charged particles.

Only a charge magnitude identical to zero is interpreted as representing a neutral particle. This avoids ambiguities that might arise from using an approximate comparison with an arbitrary epsilon.
