Member Function Documentation

◆ add_entry()

void dd4hep::detail::VolumeManager_Populator::add_entry	(	SensitiveDetector	sd,
		DetElement	parent,
		DetElement	e,
		const TGeoNode *	n,
		const Encoding &	code,
		Chain &	nodes
	)

inline

Definition at line 258 of file VolumeManager.cpp.

◆ encoding()

static Encoding dd4hep::detail::VolumeManager_Populator::encoding	(	const IDDescriptor	iddesc,
		const VolIDs &	ids
	)

inlinestatic

Compute the encoding for a set of VolIDs within a readout descriptor.

Definition at line 244 of file VolumeManager.cpp.

◆ hasSensitiveContent()

bool dd4hep::detail::VolumeManager_Populator::hasSensitiveContent ( TGeoVolume * vol )

inline

Returns true if vol or any descendant is a sensitive volume (result is cached).

Definition at line 77 of file VolumeManager.cpp.

◆ numNodes()

size_t dd4hep::detail::VolumeManager_Populator::numNodes ( ) const

inline

Access node count.

Definition at line 74 of file VolumeManager.cpp.

◆ populate()

void dd4hep::detail::VolumeManager_Populator::populate ( DetElement e )

inline

Populate the Volume manager.

Definition at line 90 of file VolumeManager.cpp.

◆ print_node()

void dd4hep::detail::VolumeManager_Populator::print_node	(	SensitiveDetector	sd,
		DetElement	parent,
		DetElement	e,
		const TGeoNode *	n,
		const Encoding &	code,
		const Chain &	nodes
	)		const

inline

Definition at line 297 of file VolumeManager.cpp.

◆ scanPhysicalVolume()

size_t dd4hep::detail::VolumeManager_Populator::scanPhysicalVolume	(	DetElement &	parent,
		DetElement	e,
		PlacedVolume	pv,
		Encoding	parent_encoding,
		SensitiveDetector &	sd,
		Chain &	chain
	)

inline

Scan a single physical volume and look for sensitive elements below.

Check if this particular volume is the placement of one of the children of this detector element. If the daughter placement is also a detector child, then we must reset the node chain.

Distinguish logically the two following cases for our understanding.... Though the treatment is identical

Definition at line 113 of file VolumeManager.cpp.

◆ update_encoding()

static Encoding dd4hep::detail::VolumeManager_Populator::update_encoding	(	const IDDescriptor	iddesc,
		const VolIDs &	ids,
		const Encoding &	initial
	)

inlinestatic

Compute the encoding for a set of VolIDs within a readout descriptor.
