Detailed Description

TGeoParser is a helper struct that walks recursively through a TGeometry and selects by string comparison the TGeoNodes that match the criteria.

It also buils up the global transform for the conversion into an ACTS Surface

Member Function Documentation

findNodeRecursive()

TGeoNode * ActsPlugins::TGeoParser::findNodeRecursive ( TGeoNode * currentNode, const char * volumeName )

static

Simple utility function that recursively finds the node by the volume name in the tgeo branch.

Parameters

currentNode	[in] the pointer to the current node in the branch
volumeName	[in] the name of the volume to be searched for

Returns

the pointer to the node corresponding to the volume

select()

void ActsPlugins::TGeoParser::select ( State & state, const Options & options, const TGeoMatrix & gmatrix = TGeoIdentity("ID") )

static

The parsing module, it takes the top Volume and recursively steps down.

Parameters

state	[out] The parsing state configuration, passed through
options	[in] The parsing options as required
gmatrix	The current built-up transform to global at this depth
