Member Function Documentation

float HepMC::HeavyIon::eccentricity ( ) const

inline

eccentricity of participating nucleons in the transverse plane (as in phobos nucl-ex/0510031)

Definition at line 110 of file HeavyIon.h.

Referenced by HepMC::operator<<(), and operator==().

bool HepMC::HeavyIon::operator!= ( const HeavyIon & a ) const

inline

check for inequality

any nonmatching member generates inequality

Definition at line 254 of file HeavyIon.h.

bool HepMC::HeavyIon::operator== ( const HeavyIon & a ) const

inline

check for equality

equality requires that each member match
