Classes
class	smash::Action
	Action is the base class for a generic process that takes a number of incoming particles and transforms them into any number of outgoing particles. More...
class	smash::Action::InvalidResonanceFormation
	Thrown for example when ScatterAction is called to perform with a wrong number of final-state particles or when the energy is too low to produce the resonance. More...
class	smash::Action::StochasticBelowEnergyThreshold
	Exception for a temporary bugfix for when multiparticle interactions do not have the necessary energy to create the final state. More...

Namespaces
	smash
	smash::detail
	specialize a type for all of the STL containers.

Functions
std::vector< ActionPtr > &	smash::operator+= (std::vector< ActionPtr > &lhs, std::vector< ActionPtr > &&rhs)
	Append vector of action pointers. More...
std::ostream &	smash::operator<< (std::ostream &out, const ActionPtr &action)
	Convenience: dereferences the ActionPtr to Action. More...
std::ostream &	smash::operator<< (std::ostream &out, const ActionList &actions)
	Writes multiple actions to the out stream. More...
void	smash::detail::sample_manybody_phasespace_impl (double sqrts, const ParticleTypePtrList &types, std::vector< FourVector > &sampled_momenta)
	Implementation of the full n-body phase-space sampling (masses, momenta, angles) in the center-of-mass frame for the final state particles, using the M-method from CERN-68-15, paragraph 9.6. More...
void	smash::detail::sample_manybody_phasespace_MCMC (const ParticleTypePtrList &types, std::vector< FourVector > &sampled_momenta)
	Metropolis–Hastings sampling of the many body phase space, starting from an initial guess in sampled_momenta that is assumed appropriate. More...

Variables
