Detailed Description

template<detail::ComparableBoundConcept BoundsType_t>
class Acts::BoundFactory< BoundsType_t >

Factory helper class to construct volume or surface bounds where the constructed bounds are cached inside the factory and if the same bound parameters are requested at a later stage the factory automatically returns the cached bounds.

This provides a simple sharing mechanism of the same bounds across multiple surfaces / volumes

BoundsRet_t

template<detail::ComparableBoundConcept BoundsType_t>

template<typename T>

using Acts::BoundFactory< BoundsType_t >::BoundsRet_t

Initial value:

 
      std::conditional_t<std::is_const_v<BoundsType_t>, const T, T>

Abbreviation of the class return type.

If the set is over const objects, the return type is const as well and non-const otherwise
