Detailed Description

AbstractVolume description inside the tracking realm. This is the purely geometrical object volume.

The Acts::AbstractVolume is constructed by giving a pointer to a Transform3D and a pointer to Acts::VolumeBounds, this implies that the ownership of the objects pointed to is passed as well. For memory optimisation, the AbstractVolume can also be constructed with shared_ptr objects.

A Acts::AbstractVolume is at first a collection class of Acts::BoundarySurface, the vector of Acts::BoundarySurface is returned by the Acts::VolumeBounds that carry a decompose method.

Boundary surfaces can be shared between AbstractVolumes to enhance automatic navigation between AbstractVolumes, therefor they are reference counted by a std::shared_ptr holder class.
