This class contains the implementation of the GDML parser associated to all the supported GDML elements.

User should never need to explicitly instaciate this class. It is internally used by the TGeoManager.

Each element process has a 'Binding' to ROOT. The 'binding' is specific mapping of GDML elements (materials, solids, etc) to specific objects which should be instanciated by the converted. In the present case (ROOT) the binding is implemented at the near the end of each process function. Most bindings follow similar format, dependent on what is being added to the geometry.

This file also contains the implementation of the TGDMLRefl class. This is just a small helper class used internally by the 'reflection' method (for reflected solids).

The presently supported list of TGeo classes is the following:

Materials:

Solids:

TGeoBBox
TGeoArb8
TGeoTubeSeg
TGeoConeSeg
TGeoCtub
TGeoPcon
TGeoTrap
TGeoGtra
TGeoTrd2
TGeoSphere
TGeoPara
TGeoTorus
TGeoHype
TGeoPgon
TGeoXtru
TGeoEltu
TGeoParaboloid
TGeoCompositeShape (subtraction, union, intersection)

Approximated Solids:

Ellipsoid (approximated to a TGeoBBox)
Elliptical cone (approximated to a TGeoCone)

Geometry:

TGeoVolume
TGeoVolumeAssembly
divisions
reflection

When most solids or volumes are added to the geometry they

Whenever a new element is added to GDML schema, this class needs to be extended. The appropriate method (process) needs to be implemented, as well as the new element process then needs to be linked thru the function TGDMLParse

		XMLNodePointer_t	node,
		XMLAttrPointer_t	attr
	)

private

In the solids section of the GDML file, an Arb8 may be declared.

when the arb8 keyword is found, this function is called, and the dimensions required are taken and stored, these are then bound and converted to type TGeoArb8 and stored in fsolmap map using the name as its key.

when the assembly keyword is found, this function is called, and the name is converted into type TGeoVolumeAssembly and stored in fvolmap map using the name as its key. Some assembly volumes reference to other physical volumes to contain inside that assembly, declaring positions and rotations within that volume. When each 'physvol' is declared, a matrix for its rotation and translation is built and the 'physvol node' is added to the original assembly using TGeoVolume->AddNode.

private

In the solids section of the GDML file, a box may be declared.

when the box keyword is found, this function is called, and the dimensions required are taken and stored, these are then bound and converted to type TGeoBBox and stored in fsolmap map using the name as its key.

Definition at line 2052 of file TGDMLParse.cxx.

◆ Cone()

XMLNodePointer_t TGDMLParse::Cone	(	TXMLEngine *	gdml,
		XMLNodePointer_t	node,

private

In the solids section of the GDML file, a cone may be declared.

when the cone keyword is found, this function is called, and the dimensions required are taken and stored, these are then bound and converted to type TGeoConSeg and stored in fsolmap map using the name as its key.

Definition at line 2624 of file TGDMLParse.cxx.

◆ ConProcess()

XMLNodePointer_t TGDMLParse::ConProcess	(	TXMLEngine *	gdml,
