Detailed Description

The base class for all dd4hep geometry crawlers.

Geometry crawlers are used for multiple purposes, whenever entire geometries must be traversed like e.g. to create a new geometry for simulation etc. While analysing the geometry, information is collected, which may be later processed.

Constructor & Destructor Documentation

GeoHandler() [1/3]

dd4hep::detail::GeoHandler::GeoHandler ( const GeoHandler &  )

inlineprivate

Never call Copy constructor.

Definition at line 105 of file GeoHandler.h.

detail::GeoHandler::GeoHandler

(

)

		std::map< int, std::set< const TGeoNode * > > *	ptr_set,
		std::map< const TGeoNode *, std::vector< TGeoNode * > > *	daus = nullptr
	)

Initializing constructor.

Member Function Documentation

collect() [1/2]

detail::GeoHandler & detail::GeoHandler::collect

(

DetElement

top

)

Collect geometry information from traversal.

Definition at line 101 of file GeoHandler.cpp.

collect() [2/2]

detail::GeoHandler & detail::GeoHandler::collect	(	DetElement	top,
		GeometryInfo &	info
	)

Collect geometry information from traversal with aggregated information.

Definition at line 109 of file GeoHandler.cpp.

i_collect()

detail::GeoHandler & detail::GeoHandler::i_collect ( const TGeoNode *  parent, const TGeoNode *  node, int  level, Region  rg, LimitSet  ls  )

protected

Internal helper to collect geometry information from traversal.

Collect the hierarchy of placements perform lookup using std::set::emplace (faster than std::find for very large number of volumes)

Now collect all the daughters of this volume, so that we can reconnect them in the correct order

Definition at line 148 of file GeoHandler.cpp.

operator=()

GeoHandler& dd4hep::detail::GeoHandler::operator= ( const GeoHandler &  )

inlineprivate

Never call assignment operator.

Definition at line 108 of file GeoHandler.h.

release()

std::map< int, std::vector< const TGeoNode * > > * detail::GeoHandler::release

(

)

Access to collected node list.

release the std::vector geometry container (preserves order)

the std::set container (for lookup purpose) is not needed anymore, so delete it the container is always present since the call of the constructor we never expect to call release() twice (will release nullptr)

Definition at line 80 of file GeoHandler.cpp.

setPropagateRegions()

bool detail::GeoHandler::setPropagateRegions

(

bool

value

)

Propagate regions. Returns the previous value.

Definition at line 95 of file GeoHandler.cpp.
