Typedef Documentation

GeoVolumeVec_t

typedef std::vector<std::pair<const GeoVPhysVol*, GeoTrf::Transform3D> > GeoVolumeVec_t

Return the child volumes and associated transforms.

Parameters

node	Root of the graph to traverse.
depthLimit	Depth limit for the traversal.
sizeHint	Hint about the number of volumes to be returned, to allow avoiding resizes of the output vector.

Returns a vector of (volume, transform) pairs for volumes in the graph. The same volume may be returned multiple times with different transforms in the case of a GeoSerialTransform.

Function Documentation

geoGetVolumes()

GeoVolumeVec_t geoGetVolumes	(	const GeoGraphNode *	node,
		int	depthLimit,
		int	sizeHint )

Return the child volumes and associated transforms.

Parameters

node	Root of the graph to traverse.
depthLimit	Depth limit for the traversal.
sizeHint	Hint about the number of volumes to be returned, to allow avoiding resizes of the output vector.

Returns a vector of (volume, transform) pairs for volumes in the graph. The same volume may be returned multiple times with different transforms in the case of a GeoSerialTransform.
