Detailed Description

template<detail::ContinuousProcessConcept physics_t, typename input_particle_selector_t, typename output_particle_selector_t, typename child_particle_selector_t = output_particle_selector_t>
struct ActsFatras::ContinuousProcess< physics_t, input_particle_selector_t, output_particle_selector_t, child_particle_selector_t >

A continuous simulation process based on a physics model plus selectors.

Template Parameters

physics_t	is the physics model type
input_particle_selector_t	is the input particle selector
output_particle_selector_t	is the output particle selector
child_particle_selector_t	is the child particle selector

The physics model type must provide a call operator with the following signature

<Particle Container>
operator()(
    generator_t& generator,
    const Acts::MaterialSlab& slab,
    Particle& particle) const

The return type can be any Container with Particle elements.

The input selector defines whether the process is applied while the output selector defines a break condition, i.e. whether to continue simulating the particle propagation. The child selector is used to filter the generated child particles.

Note

The output and child particle selectors are identical unless the child particle selector is explicitly specified.
