TGDMLParse Class Reference

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:

Approximated Solids:

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

Geometry:

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

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.
