GeoVXDAssembly createSubComponents ( const std::string &  name,
VXDGeoComponent component,
std::vector< VXDGeoPlacement placements,
bool  originCenter = true,
bool  allowOutside = false 
)
inherited

Place a list of subcomponents into an component.

If the volume of the given component is NULL, a new container will be created to fit all subcomponents. It will have air as medium. If at least one subcomponent with this placement is found the whole component is wrapped in a container volume with Air medium which extends above and below to fit the subcomponents

Parameters
nameName for the potential new volume or as prefix for the container to extend the component
componentComponent to fit the subcomponents into
placementsPlacement information for all subcomponents
originCenterbool
allowOutsidebool
Returns
offset in w which was applied to the component when extending it
